Hi,
We've had some complaints off and on about diffs taking a long time. This happens at random times, doesn't happen often and clears itself up after awhile. When this happens, the load on the Apache servers seem low and the database seems ok.
We did seem to have this problem if users had the Google toolbar installed a few months ago, but it appears that the problem is back and unrelated.
I wonder if the job queue has anything to do with it, sometimes it get's up to over 10,000 on us, but usually is at 0. I haven't been able to check what it's at when users experience this problem.
Does anyone have any ideas on how to debug, or what the possible causes might be? We're still running 1.6.7.
Thanks, Travis
