I will guess that increasing the LDAP pool size will not help much.
The psp is single-threaded, mostly because I was unsure how threadsafe
the third-party spml library is.
Most of the performance bottlenecks I have dealt with involved
eliminating unnecessary queries back to grouper.
It is difficult for me to help with performance tuning from afar, and
I am obviously not responding in a timely manner either.
In general, I would look at avoiding querying grouper for every membership.
