Re: Performance of Netmeeting/openLDAP server

Actually we too are getting some very very poor performance out of OpenLDAP.
We seem to find that searches are the killer. From what I remember there
is/was an email thread on the performance of searches. We have been screwing
around with it for some time and have had little success in getting it to
run faster. I believe it is a bug in OpenLDAP (or is it a feature?).
