You can obtain a quick idea of whether performance issues are related to problems with the server or with the client by examining the access log at install-dir/logs/access. This log contains entries of the form:

[09/Sep/2009:15:36:18 +0200] SEARCH RES conn=1 op=16 msgID=17 
  result=0 nentries=1 etime=1

The value of the etime field is the time (in milliseconds) that the server spent processing the request. Large etimes generally indicate an issue on the server side (which can usually be resolved by appropriate performance tuning or indexing. If you are experiencing performance problems but the etimes are small, the issue is more likely to be with your client application.
