you could look at PGSQL optimization - ensure that the table has the right
indexes and the table is in cache etc.

.the use 'fastusers' module instead. it'll scream along. if i dont get 5-figure
auths from such a box i'd be disappointed.

tweak your PGSQL, ensure you arent running any modules you dont need - eg the 'unix'
module which will query /etc/passwd for every single request, ensure that no logging
is blocking, ensure that accounting is buffered and not locking/blocking a thread, 
basically get the system in a working state and then tweak/optimise.
