Hi,

There could be many reasons to this behaviour, depending on other 
processes, the exact request, your Java application...

Do you see the same response times using the ldapsearch command, 
executing exactly the same search? At the same time, is it possible that 
the OpenLDAP server is in use by any other clients?
