<br>
We&#39;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&#39;s still not what we&#39;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&#39;t know if it has the same sort of scheduler behavior or not, just mentioned the vmware for context.<br>

&gt; One thing that I see jump out - you&#39;ve probably got too many virtual<br>

&gt;<br>
&gt; Try your test again dropping that to 8 virtual CPUs and I think you<br>

&gt;<br>
&gt; Particularly if this host system has other vms running on it, you&#39;re<br>
&gt; hurting the vm scheduler&#39;s ability to hand out resources. With vmware,<br>
&gt; I believe a simple rule of thumb is that scheduler requires N-1 CPUs<br>
&gt; to be locked to schedule execution of an N cpu virtual machine - so even if it doesn&#39;t need all of the CPUs, it has to reserve all of them any time you have more than a 2 vCPU vm.<br>

&gt;&gt;<br>
&gt;&gt;          Our new build is now on Debian 8 Jessie, performance on the system is noticeably better and any audio problems<br>
&gt;&gt;          while the system is under load are significantly reduced but we do still experience spikes along with reduced<br>
&gt;&gt;          audio quality when the system is processing 20 calls per<br>
&gt;&gt; second while already maintaining 80 existing calls.____<br>
&gt;&gt;<br>
&gt;&gt;          ____<br>
&gt;&gt;<br>
&gt;&gt;          We&#39;re still hitting some kind of bottleneck, what should we expect to be able to support on a single piece of<br>
&gt;&gt;          hardware? We&#39;ve kept our dialplans as small as possible and we&#39;re using Memcache, but something tells me it&#39;s<br>
&gt;&gt;          the call setup process which is triggering the spikes, is this possibly a limitation on the SIP profiles which<br>
&gt;&gt;          are single threaded?____<br>
&gt;&gt;<br>
&gt;&gt;          ____<br>
&gt;&gt;<br>
&gt;&gt;          I also see FreeSWITCH supports clustering but it&#39;s in relation to high availability, is it possible to cluster a<br>
&gt;&gt;          single FreeSWITCH instance across multiple hardware or should we be looking elsewhere to solve these<br>
&gt;&gt;          bottlenecks?____<br>
&gt;&gt;<br>
&gt;&gt;          ____<br>
&gt;&gt;<br>
&gt;&gt;          We switched to TCP Vegas on our new build as recommended on the FreeSWITCH Wiki, this has provided a noticeable<br>
&gt;&gt;          reduction in audio latency but doesn&#39;t solve the issue with<br>
&gt;&gt; CPU spikes.____<br>

&gt;&gt;              ____<br>

&gt;&gt;              We&#39;re experiencing performance issues with FreeSwitch, our target is 500 concurrent sessions, but at the<br>
&gt;&gt;              moment this starts to bottleneck around 30.____<br>

&gt;&gt;              After around 30 concurrent sessions we begin to see CPU spikes almost every time a new call comes in, as the<br>
&gt;&gt;              sessions increase the size and frequency of the CPU spikes also increase. The system seems to be able to sit<br>
&gt;&gt;              comfortably with over 100 concurrent sessions and 80% idle CPU, providing we don&#39;t have any new calls<br>
&gt;&gt;              hitting the platform. The spikes are causing audio (RTP) to stutter or in some cases drop completely for a<br>
&gt;&gt;              few seconds.____<br>
&gt;&gt;<br>
&gt;&gt;              ____<br>

&gt;&gt;              ____<br>
&gt;&gt;<br>
&gt;&gt;              We&#39;re using FreeSwitch in multi-tenant mode, we have tried dedicating a single VM for one tenancy but still<br>
&gt;&gt;              experience the issue. My assumption has been that this will be due to the dialplan, I&#39;ve optimized this<br>
&gt;&gt;              slightly by writing LUA scripts to handle some of the inbound calls this appears to take away some of the<br>
&gt;&gt;              load but we&#39;re still using the internal dialplans for each tenancy (tenancy dialplans have an average of 300<br>
&gt;&gt;              entries).____<br>
&gt;&gt;<br>
&gt;&gt;              ____<br>
&gt;&gt;<br>
&gt;&gt;              We are using the following arguments when running<br>
&gt;&gt; FreeSwitch:____<br>
&gt;&gt;<br>
&gt;&gt;              -rp -nc -nonat____<br>
&gt;&gt;<br>
&gt;&gt;              ____<br>
&gt;&gt;<br>
&gt;&gt;              I&#39;ve seen another post which says we should operate FreeSwitch in High Performance mode using -hp but can&#39;t<br>
&gt;&gt;              find anything information about this, is this still a<br>
&gt;&gt; valid argument to use with FreeSwitch?____<br>
&gt;&gt;<br>
&gt;&gt;              ____<br>
&gt;&gt;<br>
&gt;&gt;              Has anyone experienced similar performance issues before<br>
&gt;&gt; or have any advice?____<br>
&gt;&gt;<br>
&gt;&gt;              ____<br>
&gt;&gt;<br>
&gt;&gt;              Hope someone may be able help.____<br>
&gt;&gt;<br>
&gt;&gt;              ____<br>

&gt;&gt;              Thanks,____<br>
