[Fedora-directory-users] CPU utilization

[Eddie C]

The best way to handle performance issues is look in the acccess log for
notes=U. These are unindexed searches. Its amazing to add the index and then
watch the processor move from 99% to 0% thats what happened with one of our
applications.

It is definately a good idea to make different usernames for you different
applications. If you give each application a different login it later allows
you to go back and write individual ACI's. If all your applications share
the same login you will eventually have to move all applications to a
different user.

Here is a question for all. Does anyone know of a log tool specifically for
LDAP logs? I think there are big possibilites for something like this.
