I have not read the gory details on the wiki but the reads & writes being
a constraining factor should be a significant concern. How much modification
of the directory are you performing (number of LDAP write operations?) versus
reading? Are you sure your indexing and caching parameters are properly set?
Evaluating cache hit ratios during normal operation and then a grouper run
would also be useful. I hope this helps and doesn't add to the confusion.

Reducing logging had a negligible impact on performance. We're moving
the LDAP server DB & logs to a fast isSAN disk as our next step.
