What? PostgreSQL has always used the kernel cache for queries.

Well, just keep in mind when tuning that your calculations should be based on
*available* RAM, meaning RAM not used by Apache or the JVM.
With that many concurrent requests, you'll want to be *very* conservative with
sort_mem; I might stick to the default of 1024 if I were you, or even lower
it to 512k.
