Subject [jira] [Created] (DIRSERVER-1739) LDAP Searches Slow
Date Wed, 25 Jul 2012 14:30:35 GMT

-------------------------------------

             Summary: LDAP Searches Slow
                 Key: DIRSERVER-1739
                 URL: https://issues.apache.org/jira/browse/DIRSERVER-1739
             Project: Directory ApacheDS
          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
RAM : 4 GB
OS Type : 64 bit
            Reporter: Amod Kadam


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 ?
