Re: scaling openldap for performance

Hello Howard,

 Thanks for the pointers.

 Will have these patches applied to DB and re-run the
tests. 

 Do you think the seg faults/crashes would be mainly
due to issues with BDB???. Any other reasons??. Note:
These segfaults are during write tests for 20+ users
on a DB consisting of 1Lakh+ records.
