>          Issue Type: Bug
>    Affects Versions: 2.0.0-M6
>         Environment: Windows Server 2008 R2 Data Center Edition 
> Processor - AMD Opteron Processor 6282 (2.59 GHz) 2 Processors

> We are having around 32K records in LDAP store. We are having custom schema and associated
structure and data with it. 
> We are doing performance testing however our searches are very slow and taking around
250 seconds ( more than 4 minutes) to provide the results.The CPU utilization is high and
in the range of 72 % and highest being 87%. So just wondering if this is a CPU bottleneck
or not ?
> We have increased the Partition Cache size to 33000 and also kept the index size for
one of the attributes as 33000. However we did not get any performance boosts. We are not
sure if the indexing is working correctly or not. 
> It is not very clear whether 32K records is high number for ApacheDS (should not be !)
or is it due to some known issue in the ApacheDS implementation.
> Could you help ?
