Description

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 ?
