I believe that op system side buffering can play a role too. I our case, the
DB server (machine & op sys) caches data that it pulled from disk (not
necessarily from a DB) and also the disk servers do the same. If a block was
removed from the DB buffer cache to accommodate more recently request

Note that starting in 8.0/8.1, you can sometimes get very large gains
by setting shared_buffers very high; 1/2 of memory or more.

What are you timing exactly? Almost every benchmark I've ever seen is
much happier wi
