Hi!<br><br>Please note that ab itself a huge bottleneck and it gives you zero information about nginx performance. As you can see you hit the 100% CPU -what comes from ab load-.<br>I realized that during performance testing, all what I can tell you: use the httperf instead if you have a chance. <br>
(do not forget to modify the FD_SETSIZE to higher value)<br><br>Regards,<br>Istvan<br><br><div class="gmail_quote">2009/4/21 Weibin Yao <span dir="ltr"><<a href="mailto:nbubingo@gmail.com">nbubingo@gmail.com</a>></span><br>

It seems that the most suitable concurrency for my PC is 1-200.<br>
