<p class="MsoNormal">Update<br>
<br>
We've performed various tests and have come to the conclusion as advised by others, that visualization is causing bottlenecks.<br>
<br>
Using Amazon EC2 on an 8 core high performance virtual server this maxed out at around 800 concurrent sessions, 400 sessions per second.<br>
<br>
Using a Dell 1950 8 core server this was able to handle 1000 concurrent sessions, 400 sessions per second and still have plenty of resource available. Average CPU was fluctuating between 30-40% under peak load.<br>
<br>
Conclusion, if you want to run a high performance FreeSwitch server in a production you should stick with physical hardware and avoid visualization where possible.<br>

Hi Nathan,<br>
<br>
Thanks for the suggestion, we still see the CPU spikes when is under load after reducing to 8 cores but I think there may actually be an improvement in the audio quality.<br>
<br>
It's still not what we're expecting, so we will have to test our build on physical hardware too.<br>
<br>
Thanks,<br>

Yes, I know you said Hyper-V, I don't know if it has the same sort of scheduler behavior or not, just mentioned the vmware for context.<br>
