Not to mention that it is horribly inefficient to be running windows and Linux on the same machine if you are trying to get good performance out of your Asterisk server.
Yeah, thats what I figured out. I'm actually using Microsoft's Virtual Server not VMWare but I'd expect the same results. FYI, zttest showed around 95% (8192 samples in 8454 sample intervals 96.801758%) and the meetme latency was about 1 second from the time a speaker was heard by a listener.
It was an experimental build to see if the product is suitable for my company. We have found it to be great and have started installing it on real hardware.
I think Asterisk is actually very usable in a proper VM environment, as long as there is no need to use meetme or other things which require timing OR we use TDMoE.
I wonder has anyone approached VMWare about creating a timer hook or something for these types of RT applications?
