Help with an LDAP autopsy...

[Chris van der Merwe <chris@arnes.si>]

I've setup a SUN enterprise server to test the HEAD code and the new hdb 
backend. I'm using the DirectoryMark software to run benchmark tests.
I have created a test directory of 40,000 items and I've started with a 
test searching for uid (this is the standard DirectoryMark test avaiable 
via the -u option in scriptgen.pl - I specified originally 5 threads of 
1000 searches each and then chose 1 thread of 1000)
Originally I wanted to test with 5 threads for a beginning, but I it was 
crashing, so I took it down to 1 thread and debugged the LDAP server.

Unless I'm reading the results wrong, it looks like the LDAP server is 
not even managing to get through one pass of the data whilst searching 
for a uid before it just hangs and refuses to do anything for about 300 
seconds....

Does anyone have any ideas what could be amiss here?

Thanks
 Chris
