[HOW TO]How to increase your Internet Speed

Sponsored Links

Here are Registry Tweaks and Scroll down to see Patches

1.Increase bandwidth by tweaking QoS in Windows XP Pro

The following tweak applies only to Windows XP Professional edition.

The default system behavior is that all 100% bandwidth is available, however, if there is a running

application that indicates to the OS it needs to send high priority/real time data, then as long as it has the

socket open, Windows XP will restrict best eort trac to 80% of the bandwidth so that high priority

trac can be accommodated. Basically, applications can make this request to the operating system for

QoS support using the QoS application programming interfaces (APIs) in Windows and this only applies if

a specic app is requesting QoS.

If youd like to change how much bandwidth is reserved for QoS (the default is 20% of the total

bandwidth), do the following:



1. Make sure youre logged in as Administrator (not just any account with admin privileges).

2. Navigate to START>Run and type: gpedit.msc

3. Navigate to Local Computer Policy > Administrative Templates > Network > QOS Packet Scheduler

4. In the right window, double-click the limit reservable bandwidth setting

5. On the setting tab, check the enabled setting.

6. Where it says Bandwidth limit %, change it to read 0 (or whatever percentage you want to reserve for

high priority QoS data)

7. Click OK, close gpedit.msc

Under START > My Computer > My Network Connections > View Network Connections, right-click on your

connection and under Properties (where it lists your protocols), make sure QOS Packet Scheduler is

enabled.

The tweak desribed below helps boost priority for DNS & hostname resolution in general. What this

means is, it helps web pages load faster, and has negligible eect on downloads (not counting the couple

of ms gain with the host resolution at connect-time).

Applying this tweak assumes some prociency in editing the Windows Registry using Regedit (Start > Run

> type: regedit). As always, backup your Registry before making any changes so you can revert to the

previous state if you dont like the results.

2.Host Resolution Priority Tweak

host name resolution priority

Windows 2k/XP

First, open the Windows Registry using Regedit, and (after backing up) navigate to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\ServiceProvider

Note the following lines (all hex dwords):

Class = 008 (8) indicates that TCP/IP is a name service provider, dont change.

LocalPriority = 1f3 (499) local names cache

HostsPriority = 1f4 (500) the HOSTS le

DnsPriority = 7d0 (2000) DNS

NetbtPriority = 7d1 (2001) NetBT name-resolution, including WINS

What were aiming to do is increase the priority of the last 4 settings, while keeping their order. The valid

range is from -32768 to +32767 and lower numbers mean higher priority compared to other services.

What were aiming at is lower numbers without going to extremes, something like whats shown below

should work well:

Change the Priority lines to:



LocalPriority = 005 (5) local names cache

HostsPriority = 006 (6) the HOSTS le

DnsPriority = 007 (7) DNS

NetbtPriority = 008 (8) NetBT name-resolution, including WINS

Windows 9x/ME

The tweak is essentialy the same as in Windows 2000/XP, just the location in the Registry is slightly

dierent. For a more detailed description see the Windows 2000/XP section above.

Open the Windows Registry using Regedit, and (after backing up) navigate to:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP\ServiceProvider

You should see the following settings:

Class=hex:08,00,00,00

LocalPriority=hex:f3,01,00,00

HostsPriority=hex:f4,01,00,00

DnsPriority=hex:d0,07,00,00

NetbtPriority=hex:d1,07,00,00

The priority lines should be changed to:

LocalPriority=hex:05,00,00,00

HostsPriority=hex:06,00,00,00

DnsPriority=hex:07,00,00,00

NetbtPriority=hex:08,00,00,00

Reboot for changes to take eect.

In addition to the tweaks already covered in Win 2k/XP Registry Tweaks and More Win 2k/XP Tweaks, the

Windows XP Service Pack 2 introduces a few new issues covered in the article below. Please make sure

you understand what you are doing before making any changes to your Operating System. Note the

information below only applies to Windows XP Service Pack 2.

3.Remove the limit on TCP connection attempts

Windws XP SP2 introduces a few new twists to TCP/IP in order to babysit users and reduce the threat of

worms spreading fast without control. In one such attempt, the devs seem to have limited the number of

possible TCP connection attempts per second to 10 (from unlimited in SP1). This argumentative feature

can possibly aect server and P2P programs that need to open many outbound connections at the same

time.

Rant: The forward thinking of Microsoft developers here is that you can only infect 10 new systems per



second via TCP/IP ?!? If you also consider that each of those infected computers will infect 10 others at

the same rate:

second 1: 1+10 computers

second 2: 10+10*10 computers (110 new ones)

second 3: 10+100*10 computers ( 1110 new ones)

second 4: 10+1000*10 computers (11110 new ones)

.

all the way to 10*60 + 10^60 computers in a single minute (thats a number with 60 digits, or it would far

exceed Earths population). Even if we consider that 90% of those computers are unreachable/protected,

one would still reach ALL of them within a minute.

In other words, even though it is not going to stop worm spreading, its going to delay it a few seconds,

limit possible network congestion a bit, and limit the use of your PC to 10 connection attempts per

second in the process ! I have no problem with the new default setting limiting outbound connection

attempts. Still, users should have the option to easily disable or change this setting. I might be going out

on a limb here, but ever since the introduction of Windows XP I cant help thinking that I dislike all the

bult-in Windows wisardry in a sense that the system also limits user access. That irritating trend to ease

the mental load on end users is somewhat insulting, considering that Windows is to make the more

intelligent choice instead of the end user, as well as limit their access to tuning such settings

End of rant.

With the new implementation, if a P2P or some other network program attempts to connect to 100 sites

at once, it would only be able to connect to 10 per second, so it would take it 10 seconds to reach all 100.

In addition, even though the setting was registry editable in XP SP1, it is now only possible to edit by

changing it directly in the system le tcpip.sys. To make matters worse, that le is in use, so you also need

to be in Safe mode in order to edit it.

You only need to worry about the number of connection attempts per second if you have noticed a

slowdown in network programs requiring a number of connections opened at once. You can check if

youre hitting this limit from the Event Viewer, under System look for TCP/IP Warnings saying: TCP/IP

has reached the security limit imposed on the number of concurrent TCP connect attempts. Keep in

mind this is a cap only on incomplete outbound connect attempts per second, not total connections.

Still, running servers and P2P programs can denitely be aected by this new limitation. Use the x as

you see t.

To change or remove the limit, you can use the following program:

Event ID 4226 Patcher v2.11

http://www.speedguide.net/les/xp_sp2/EvID4226Patch211a-en.zip

- A patching program for removing or changing the limit imposed on connection attempts in SP2. The

patcher has the ability to restore tcpip.sys back to the original Still, you might want to back up



tcpip.sys, use it at your own risk. The author of this patch can be reached @

http://www.lvllord.de/

4. Recommended settings for Windows 2000 / XP

Windows 2000 & XP, unlike NT supports large windows as described in RFC1323 ( the RcvWindow has a

maximum value of 2**30 rather than 64K), and includes some other improvements over its predecessors

you can use to speed up any TCP/IP transfers. , the descriptions and other options are added to provide

you with better understanding and enable you to customize your settings.

All the following entries, unless otherwise noted should be placed in the Windows 2000/XP Registry under

the key

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

TCPWindowSize

The value of TCP Window in the Windows 2000 Registry is DWORD, representing number of bytes, with

range from 0 to 2^30. The recommended values (in red) optimize TCP for any high speed Internet

connection and work best in most cases, however if youd like to use a custom value follow these

guidelines:

For best results, the TCPWindow should be a multiple of MSS (Maximum Segment Size). MSS is generally

MTU 40, where MTU (Maximum Transmission Unit) is the largest packet size that can be transmitted.

MTU is usually 1500 (1492 for PPPoE connections). To determine the MTU value of your ISP, check out the

Advanced Registry Editing section of our site.

There are three places in the Windows 2000 Registry where you can add the TCP Window parameter.

HKLM/SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

GlobalMaxTcpWindowSize=256960 (DWORD, number of bytes) Valid range is from MSS to 2^30. Add the

value as a decimal. Note: For best results RWIN has to be a multiple of MSS lower than 65535 times a scale

factor thats a power of 2, i.e. 44 x 1460 = 64240 x 2^2 = 256960. If you choose to use a RWIN lower than

65535, you can simply make it multiple of MSS and turn scaling o (Tcp1323Opts=0)

HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

TcpWindowSize=256960 (DWORD, number of bytes) Valid range is from MSS to 2^30. Add the value as a

decimal. TcpWindowSize can also exist under TcpipParametersInterface if added at this location, it

overrides the global setting for this particular . Note (10/20/00): Seems MS has found another bug in

Windows 2000, the TCPWindowSize should be congured with the global setting

(GlobalMaxTcpWindowsSize) rather than this one Q263088



Note: For best results RWIN has to be a multiple of MSS lower than 65535 times a scale factor thats a

power of 2, i.e. 44 x 1460 = 64240 x 2^2 = 256960. If you choose to use a RWIN lower than 65535, you can

simply make it multiple of MSS and turn scaling o (Tcp1323Opts=0)

Tcp1323Opts

Tcp1323Opts is a necessary setting in order to enable Large TCPWindow support as described in RFC

1323. Without this parameter, the TCPWindow is limited to 64K.


Tcp1323Opts=1 (DWORD, recommended setting is 1. The possible settings are 0 Disable RFC 1323

options, 1 Window scaling but no Timestamp options, 3 Window scaling and Time stamp options.)

Note: Tcp1323Opts=3 might help in some cases where there is increased packet loss, however generally

youll achieve better throughput with Tcp1323Opts=1, since Timestamps add 12 bytes to the header of

each packet.

DefaultTTL

DefaultTTL determines the time in seconds and the number of hops a packet lives. While it does not

directly aect speed, a larger value increases the amount of time it takes for a packet to be considered

lost, discarded and retransmitted. A value thats too small can cause packets to be unable to reach

distant servers at all.


DefaultTTL=64 (DWORD, recommended setting is 64. Other settings that are widely used are 128 and 32)

EnablePMTUDiscovery

When set to 1 (True), TCP attempts to discover MTU automatically over the path to a remote host.

Setting this parameter to 0 causes MTU to default to 576 which reduces overall performance over high

speed connections. Note that this setting is dierent than our Windows 9x recommendation.


EnablePMTUDiscovery=1 (DWORD boolean, valid settings are 0>False and 1>True. Many

connections perform better with this entry at 1, however, if you prefer to set your upstream to send xed

1500 packets, you might want to use 0 instead). When set at 1, establishing connections and initial

transfer speed might slow down a bit, however you will get better throughput if somewhere in the path

large packets need to be fragmented.

EnablePMTUBHDetect

Setting this parameter to 1 (True) enables black hole routers to be detected, however it also increases



the maximum number of retransmissions for a given segment. In most cases youd want to keep

BHDetect to 0 (False).


EnablePMTUBHDetect=0 (DWORD boolean, valid settings are 0>False and 1>True. Recommended

setting is 0)

SackOpts

This parameter controls whether or not SACK (Selective Acknowledgement) support is enabled, as

specied in RFC 2018. SACK is especially important for connections using large TCP Window sizes.


SackOpts=1 (DWORD boolean, recommended setting is 1. Possible settings are 0 No Sack options or

1 Sack Option enabled).

TcpMaxDupAcks

This parameter determines the number of duplicate ACKs that must be received for the same sequence

number of sent data before fast retransmit is triggered to resend the segment that has been dropped

in transit.


TcpMaxDupAcks=2 (DWORD range 1-3, recommended setting is 2).

Patches

This Includes

1. sguide_tweak_2k.zip

Description: Generic patch for Windows XP and Windows 2000 (all versions). This patch will optimize your

TCP/IP Registry settings for high speed Internet connections. To install, extract the .inf le rst, then

double-click (or right-click on lename and choose install from the pull-down menu) and reboot for

changes to take eect.

http://www.speedguide.net/les/sguide_tweak_2k.zip

2.sguide_tweak_2k_pppoe.zip

Description: Generic patch for Windows XP/2000 and DSL connections using PPPoE. This patch will

optimize your TCP/IP Registry settings for high speed Internet connections. It is specically designed for

PPPoE DSL connections. To install, extract the .inf le rst, then double-click (or right-click on lename

and choose install from the pull-down menu) and reboot for changes to take eect.



http://www.speedguide.net/les/sguide_tweak_2k_pppoe.zip

3. winxp_dnscache.zip

Description: Patch Windows 2k/XP not to cache failed DNS entries. By default, when a DNS lookup fails

(due to temporary DNS problems), Windows still caches the unsuccessful DNS query, and in turn fails to

connect to a host regardless of the fact that the DNS server might be able to handle your lookup seconds

later. This patch xes the problem by conguring the DNS client to continue sending queries to an

unresponsive network. To install, save to your HD, unzip the .reg le, then double-click the lename.

Web Patches faster loading of Web Pages

The following patch increases Web page loading speed, by doubling the number of possible concurrent

open connections. For example, imagine a web page has 20 images and some text in order for your

browser to get all these les, it opens 2 or 4 concurrent connections, depending on the Web server.

Increasing the number of open connections allows for faster retrieving of the data. Please note that the

patch sets some values outside of the HTML specs. If you decide to install it, backup your Registry rst.

Changes will take eect after you reboot. Download the patch appropriate for your OS:

OS: Windows 9x/ME

http://www.speedguide.net/les/sg_webtweak_9x.zip

OS: Windows 2K/XP/2k3

http://www.speedguide.net/les/sg_webtweak_2k.zip

TCP OPTIMISER

Description: The TCP Optimizer is a free, easy Windows program that provides an intuitive interface for

tuning and optimizing your Internet connection. Just download and run, there is no installaion required.

The program makes it easy to nd the best MTU and RWIN values, test latency and tweak all the

important broadband related registry parameters. The Optimizer can be helpful with tuning any Internet

connection type, from dialup to Gigabit+

Comments are closed.

The QOS tweak is a MYTH.

By default 100% of bandwidth is available to applications. An application can request priority bandwidth.

However, and contrary to the article, there will be no reduction in bandwidth unless the reserving

application is actively using it. Any unused bandwidth will be available to other applications.

Incidentally, Automatic Update does not use QOS. It actually has lower priority here than other

applications.

Any administrative account can make the change, not just the Administrator account. Disabling the QOS

service will also work. But nothing will be gained.
