<p><tt><span style="font-size:10.0pt">A successful stress test should highlight a bottleneck that we are no longer able to easily fix. Common bottlenecks with any network server application will always include:</span></tt><o:p></o:p></p>
<p><tt><span style="font-size:10.0pt">- CPU</span></tt><o:p></o:p></p>
<p><tt><span style="font-size:10.0pt">- I/O (disk / network)</span></tt><o:p></o:p></p>
<p><tt><span style="font-size:10.0pt">Most often, disk writes are to blame, either through stderr or syslog. You will definitely want a very low logging level (log_level = 1) when doing thousands of CPS, as even a single log line per request can lower the overall
throughput.</span></tt><o:p></o:p></p>
<p><tt><span style="font-size:10.0pt">Choosing the right compile flags can also help. You should print the output of "opensips -V", maybe improvements can be made.</span></tt><o:p></o:p></p>
<p><tt><span style="font-size:10.0pt">To conclude, please try to understand the bottleneck first (by using "top", "netstat", "vmstat", etc.), then we can start working on it!</span></tt><o:p></o:p></p>
