Subject: Re: Plea for help with search performance

can you provide a little more info:

1. version of the server (ApacheDS windows 2.0.0-M6)
2. OS version Windows 2008 DataCenter / 24 GB memory. 
3. what is the ~size of each entry  - Don't know how to determine the size but in the previous
email I included a LDIF entry. I'm not storing jpeg data, certificates, anything with any
length. Just simple text and numeric attributes. 

and finally are you using filters with exact match or substring match?
Not sure understand ..  I search exact and substring like this:
(employeeNumber =jsmith)  <- this is exact
(displayName =Smith, J*)  <- this is substring

Is there a way to specify that the input is an exact match or a substring, or does the parser
know that if the value has * on the end, then it's a substring?
