These servers was installed with version FreeSWITCH Version 1.3.13b+git~20130215T194756Z~9733740cab (git 9733740 2013-02-15 19:47:56Z) and they have been running fine with 250% cpu (out of 2400%), load average hits 3 at peak. </div><div><br></div><div>We wanted to get our Freeswitch onto a stable release and thought 1.2.12 was the most stable version so this is what we installed on one server. This servers cpu is at 800-900% and load average hits 10 when the server runs with 1.2.12, if we rollback cpu goes back to old 2-300%.. Call quality is still ok but I feel we have less room for more load and upgrading should normally improve performance not decrees performance. Just as an experiment I also tried to install latest 1.4 thinking this might have been something in the 1.2 branch but 1.4 acts the exact same.</div><div><br></div><div>here is a quick vmstat snapshot:</div><div><br></div><div><div>procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu----</div><div> r b swpd free buff cache si so bi bo in cs us sy id wa</div><div>15 2 0 430144 321280 9988432 0 0 3 33 1 1 11 3 87 0</div><div> 7 0 0 425160 321344 9991936 0 0 56 116 67726 113824 30 4 66 0</div><div>22 0 0 424380 321368 9993580 0 0 28 0 84236 148377 25 4 70 0</div><div>19 0 0 423656 321404 9994324 0 0 32 0 61714 103954 23 2 74 0</div><div> 9 0 0 422740 321444 9996020 0 0 24 1524 52116 86355 23 2 74 0</div><div> 7 0 0 421908 321456 9997160 0 0 20 5524 58977 98786 22 2 76 0</div><div>10 0 0 420812 321464 9998244 0 0 4 0 52964 83640 23 2 75 0</div><div>21 0 0 417152 321496 9999184 0 0 56 36 73430 124669 25 3 71 0</div><div> 6 0 0 417496 321516 10000704 0 0 20 0 78778 134441 27 3 69 0</div><div><br></div><div>This is from sometime, same calls but from a freeswitch 1.3 server:</div><div><br></div><div><div>procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu----</div><div> r b swpd free buff cache si so bi bo in cs us sy id wa</div><div> 3 0 244 2668752 269200 4589652 0 0 7 60 1 0 14 3 83 0</div><div> 4 0 244 2666192 269228 4590676 0 0 64 12 44941 50134 24 4 72 0</div><div> 3 0 244 2670200 269256 4592680 0 0 28 24 62350 86122 34 4 62 0</div><div> 4 0 244 2668584 269280 4593848 0 0 20 0 43495 53052 27 2 70 0</div><div> 6 0 244 2664636 269332 4595884 0 0 32 5576 53941 67240 26 4 70 0</div><div> 8 0 244 2665316 269380 4596720 0 0 40 68 66434 91266 31 4 64 0</div><div> 3 0 244 2666780 269404 4597792 0 0 24 0 41862 48055 23 3 74 0</div></div><div><br></div><div><br></div><div><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><br>--</div><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><b>- Freddy</b></div></div></div></div></body></html>
