</div></div>I do not think that using libev in nginx will change anything.<br>
<br>
Probably, the following settings may slightly improve or worsen:<br>
<br>
1) turing sendfile off: it may be not effective on small files.<br>
Also not that lighttz does not read file at all each request.<br>
<br>
2) using open file cache, it saves 3 syscalls per request (open, fstat, close):<br>
<br>
open_file_cache max=1000 inactive=20s;<br>
open_file_cache_valid 30s;<br>
open_file_cache_min_uses 2;<br>
open_file_cache_errors on;<br>
<br>
3) using buffered log:<br>
<br>
access_log /path/to/access.log buffer=32k;<br>
<br>
or turing it off at all:<br>
<br>
access_log off;<br>
<br>
4) using 1 worker.<br>
