The ldap process periodically shows high CPU utilization. It will gradually climb from an extremely low number to up to 95%, then gradually return to an extremely low number again.

The server is running ldap to authenticate for a Plone/zope for which the user needs to log in.

In this instance the process is extremely low. However at times it can reach 85%. During these times, the login process can take up to 30 seconds. It seems when the utilization is low, the login process is only 1 second.
