I have bad experience with combination Opteron + RTP (choppy audio). I think this is due to the size of the cache, for example for your 6128 is 128KB per core and, for example, for a Xeon E5649 is 12Mb per core. I own a 4 x Opteron 6176 (4 x 12 core) and after many tries to use it as Freeswitch server, now I&#39;m using it as database server...<div>

things appear to be running better today (fewer calls that have a sporadic<br>
choppy audio). The server load is lower, but it is not where I would like to<br>
see it. The load is around 10 on average. I think that this might be due to<br>
the fact that I have &quot;enable-clock-nanosleep&quot; set to true. I am going to try<br>
disabling this and see if the load decreases.<br>

The timer_test results are more consistent and regular; a lot closer to the<br>
20ms that you would expect to see.<br>
