#705 Saving the results of an enumeration takes far too much time

Closed: Fixed Opened Dec 10, 2010 by sgallagh.

For an LDAP server of even a moderate number of users (~5000), it can take multiple minutes to save the entries to the LDB cache.

During this save action, all other reads of the LDB are blocked, causing poor responsiveness in the SSSD. We need to perform a careful analysis of how we're saving the data and identify if there are ways that we can make this transaction perform more quickly or at least in a less-blocking manner.

Ticket #658 may aid in this.

An observation: I installed 0.2010120820git583a018.el5 the other day.
Since the update did not go smoothly - the SSSD did not stop, I got stuck and had to clean the mess manually. I enabled the enumeration and it really took several minutes to resolve approximately that amount of entries. I am running debug 9 so I looked at the log. It really spat a lot of debug data there so I thought that performance degradation is related to the level of verbosity however it might not be entirely true.

May be have an option to run scheduled enumerations (once we sort out calendaring)?
