poor openLDAP performance

I have very little experience with LDAP servers, but I think that my openLDAP server is pretty slow. Granted there are about 2000 entries in it, but I would think that a database running on a modern machine could spit all that out very quickly. When I run a LDAP browser, for instance, it "populates" pretty slowly. I can see each entry being added one by one. When I try performing a search for a name in outlook express it times out (with a 2 minute limit). If I go to advanced search and search for an exact name match it is pretty quick, as expected. I have the cn attribute indexed in several different ways (approx, eq, etc) but it still seems slow.

Do you guys have any tips to speeding up the server?

Thanks,
larman

you can have a look how openldap stores its data. iirc there are several possible backends for openldap, try experimenting whith those.
(gdbm, etc ..)

Well I had done all the performance tweaks that were mentioned in the FAQ, but none of them seemed to really help. It turns out that there was a process running on the box consuming 92% CPU. I killed that and everything flew.
I feel kind of dumb
