<p>I am not amused by your comment. </p>
<p> If you want to mock my advise then stop asking for help. Someday you will learn that ddos with sipp is not the same as real traffic but this thread is now closed.</p>

<div dir="ltr">Dmitry, Hi!<br><br>Running with -np at 180CPS for 3000sec now (over 500k calls). I already passed by far the amount of calls i was able to do at this CPS previously. <br>I can see that all FS threads are the same priority and there are no RT threads. <br>
Context switches per ser are rising slowly. If i can make a million calls it is good enough for me. <br>There is a small mem leak but that is not what have me worried because i can monitor it and restart FS when necessary. <br>
In my previous tests when CS reached closer to 60k the spiral down began. <br><br>You think that FS RT threads slowly starve another important task?<br><br>Holding my fingers crossed. <br><br>Thanks!<br>Boris Ratner.<br>
