Please don't top post.
Anyway, are you sure that increasing shared_buffers that high is
helping? There's some evidence that windows pgsql can't use
shared_buffer settings that high efficiently. Have you tested
shared_buffer settings starting low and working you way up and seen a
steady increase in performance? Or are you just guessing that larger
shared_buffer = better performance?
I'm guessing that it's a limitation of windows and pgsql that you're
running into. If you want to run a large memory postgresql database
server with lots of load, I highly recommend using unix as the
underlying OS, as pgsql is far better tested and supported there.
