Internet Network peering locationsSite data is published at http://www.peeringdb.com/view.php?asn=8075

Some cities have multiple peering points

Peering locations may be on-net or off-net

Peering may involve physical connection and/or routing advertisements

Demo 2: Measure RTT to Office 365

On dmarre 172418

Measure Internal and External RTT (TCP Ping here)

Source: How to measure the Network Round Trip Time to Office 365 by Paul Collinge

Internal should be less than 100 ms, ideally 50 msEMEA to EMEA should be less than 150 ms

Outlook in cached mode can cope well with worse RTTBut for SharePoint 350 to 400 ms is the tipping between good and bad performancesaka Edge or Egress point

Front end Caching in SPO :a huge problem for MS

51

Use Azure Redis CacheUse the Azure Redis cacheEx to store session state data like to SharePoint contextBy default the SharePointContext class requires ASP.Net session state

In Proc mode ->not ok if several ASP.Net servers
