Another way to look at it is how many page requests
Squid/Varnish can
eliminate from Apache. In our MediaWiki Squid has an average cache hit
rate of 85% which means the Apache page requests is 6.5x smaller. For
small wikis this isn't a big deal but as you scale up reducing Apache
requests by a factor of 6 is huge. Since RationalWiki appears to be
kinda of in the middle you just have to ask yourself whether page
access numbers or the Apache load is more important.
Indeed. If you've got caches in front of Apache, you won't even
increment the hit counter on many requests. It's why our reports
are pulled from the squid logs themselves.
