<div>Hi Brian,</div>
<div><br>
</div>
<div>You're absolutely right, we'd have to double check our configuration on Amazon EC2 to understand why the calls were only lasting 2 minutes. I suspect we didn't increase our sessions per second limit in FreeSwitch, new sessions are rejected when the limit
is reached but I've noticed FreeSwitch does still report on these in SIP status.</div>
<div><br>
</div>
<div>Obviously it's never going to be a fair comparison to real world as there are many other factors which can play a role in a normal environment, but in our case we seem to be hitting capacity problems with call volume. We can see that both Amazon EC2 and
physical hardware perform better than our existing Hyper-V platform.</div>

<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>

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>
