[389-users] ldapsearch performance problem

Hi all,

while moving 389ds server to another machine (and another version) I
realize performance issues during ldapsearch.

Normaly a query ist quite quick (about 20ms - but sometimes(like every
five seconds) it hangs for one ore even several seconds).

I test this with:

time ldapsearch -h localhost ...

Since the new server should be a log faster (cpu, io) I'm wondering
about what can cause this.

There is a replication with three servers and suppier-supplier config
among each. We have about 50 databases but each only maximum with a few
hundred records. Most of them smaller.

I looked for cache configuration - but these are similar to the old
server and I get entrycachehitratio about 99%.

Any idea for further debugging?
Regards
Jan
