WHY DID VARNISH WORK SO WELL?WHY DID VARNISH WORK SO WELL?Processing PHP takes resources so caching that data makesthe server more efficient.

Data is being served directly from RAM.

WHAT HAVE WE LEARNED?WHAT HAVE WE LEARNED?Varnish is your friend.

If you can't use varnish, use a host with SSDs, cache with W3Total Cache, and use a CDN.

Every extra bit of processing will hurt your site.
