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.

There's a lot more to it than that, and it is indeed a performance
drain (which is why we don't use it at WMF). Each pageview
writes to the hitcounter table. Every so often the page table is
updated with the hits from hitcounter.
Sure, displaying the hits is a simple query to the page table,
but updating hitcounter each pageview just does not scale.
