[Opensim-users] Possible to configure how often sim diagnostics are done?

[Dahlia Trimble]

Sounds to me like you're low on system memory. Try closing some other
applications, especially web browsers with lots of open tabs. Also try
lowering graphics quality and draw distance in your viewer. If it's Windows
and you haven't rebooted for a while. virtual memory can get rather
fragmented and usually use up a lot of swapping time when Windows decides
to move things around. A reboot can help when this happens.

I'd guess that the timer driven diagnostic might trigger a page swap to
bring in a part of opensim that had been swapped out, and that might
trigger the operating system to move a lot of stuff around which will lock
up the system for a while. You probably don't see it with the "show stats"
command as those pages might already be resident in memory when you invoke
the command.
