Right now we have seventy calls waiting in queues (all with native MOH)

more than 0.8% CPU.
Personally, I wouldn't mind seeing an option that allowed native MOH to
pull from a single thread for each class. It would probably yield lower
CPU utilization, but I'm not sure how difficult it would be to
implement. If enough people are interested in this feature, it should
be submitted through Mantis as a feature request.
Wow ... that's some pretty heavy call utilitization... ok good to
know. With 6 calls on hold I'm seeing about 0.2% CPU used. It just
seems like opening a new thread for every MOH instance will use more
disk i/o as well.
Matt,
I was considering moving the MOH files to a RAM disk at boot and then
playing them from there to handle that problem. I'm not sure it's
necessary, though. Currently, QueueMetrics is showing 100 callers in
queue, but iostat is showing almost no read activity on the disk. My
guess is that Linux is already caching the files to memory. Of course,
this is entirely dependent on the amout of memory in the system.
