<div dir="ltr">my test results using sipp script + FreeSWITCH docker container + PCMU on c5.4xlarge instance only audio stream. Each call duration is 200 seconds.<div>Tested Kazoo all-in-one install. So, here some overhead exit for Elang components.<br><br>According to load test on c5.4xlarge Amazon instance after 282 seconds is reached 1258 simultaneous calls at 6 calls per second rate. During the test all calls and registrations are successful. During the test CPU load is reached 79% value, memory usage 7Gb, and 150 mb/s total network usage over all docker containers on "all-in-one" Kazoo configuration.<br></div><div><br></div><div>Sergey</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Oct 11, 2020 at 1:51 PM <<a href="mailto:ziv@ip-com.co.il">ziv@ip-com.co.il</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div lang="en-IL" style="overflow-wrap: break-word;"><div class="gmail-m_-3591899684814614505WordSection1"><p class="MsoNormal"><span lang="EN-US">Hi,<u></u><u></u></span></p><p class="MsoNormal"><span lang="EN-US"><u></u> <u></u></span></p><p class="MsoNormal"><span lang="EN-US">We run FreeSWITCH on Amazon AWS EC2, using the c5.xlarge machine size, meaning 4 CPUs with hyper-threading, sums up to 8 vCpu.<u></u><u></u></span></p><p class="MsoNormal"><span lang="EN-US">In time of high-traffic, the system is reaching 100% CPU at about 400 concurrent sessions, which is typically 200 calls (2 sessions per call).<u></u><u></u></span></p><p class="MsoNormal"><span lang="EN-US">RTP is sent as G-711.
