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?

1 *million* addition per second ? Either you have an issue with the unit you use, or there is something wrong going on but you didn't noticed the problem...

All my experience with OpenLDAP so far shows x86 servers far outperforming Sun T2000s, given comparable memory and disk. The individual Sun cores are just too slow.

1MB/second vs 50kb/second.
