I have OpenLDAP 1.2.7/BDB 2.7.7 compiled --with-treads=posix on an IPC
running solaris 2.6.

The database has about 1500 entries for users in it and it takes 6.75
seconds to do the following query:


On a SPARCstation 5 it takes less than a second for the same thing and
on any flavour of Ultra it is INSTANT. The limiting factor with ultra's
is the speed of the network, not the LDAP server.

The important things in the config file are:
cachesize       256
dbcachesize     25600
