I'm evaluating OpenLDAP on various platforms and am having trouble getting the tools (slapadd, slapindex, etc) to perform well on Sun's T2000 servers.  For example slapadd is running at about 50k/s.  On an x86 server importing the same ldif yields over 1M/s.  Using Berkeley DB 4.8 backend.  I'm assuming the problem is related to CPU speed and threads.  Can anyone give me some tips to increase the performance on this platform?
