Can we see your access log showing the slow searches? Are they
unindexed? If you have unindexed searches they will bog down the entire
server. Do you see high cpu for ns-slapd?
Can you also run logconv.pl?
logconv.pl -ulatn /var/log/dirsrv/slapd-YOUR_INSTANCE/access*
Thanks,
Mark

Hi all,
we are still suffering from this poor performance problem. Any hint for
further debugging are welcome.
As this 389ds installation is part of an kolab multidomain setup we habe
about 50 separated database backends each replicated with two other servers.
The symtop is - depending on queries: sometimes everything is lacking
for several seconds (up to 3 or 4 and worse).
389ds is version 1.3.3.5-4 and runs on a xen 4.8 domU.
Load is not high neigher disk io at all. Everything else on the machine
or other xen-domains is running fine.
any idea?

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
