milestone: SSSD 1.6.0 => NEEDS_TRIAGE

This request has been coming from several different users running in different environments. I would propose that we gather as much info from the users before we decide on where to optimize.

I think that a systemtap script that generates a callgraph with statistics about how much time do we spend in different functions and perhaps how much time we spend waiting on I/O (both disk and network) would help us here. Then we would at least know whether we should spend time parallelizing the lookups or perhaps profiling the memberof plugin some more..

Replying to [comment:5 mmoeller]:

Marcus, can you measure how slow initgroups are for you?

I would like to ask you to:
1. clear the caches
2. run "id -G $username"

The -G parameter is important - that would make sure only initgroups is performed and "id" would then output the GID numbers of the groups user is a member of. Without the -G parameter, "id" then calls getgrgid() on all the group GIDs which may be very slow (and may not be fixable).

Thank you!

Also when running the test, would you mind telling us how big the group structure is? In other words, how many groups does the user belong to?

The issue is already fixed in 1.6. The bug was reopened by mistake.
