Hello Everyone!
I have a Apache 2.2 server running ab php5, mysql forum,with CentOS 4.4.
Most of my visitors are from our intranet.
The problem is, sometimes, the pages is hardly to open,and sometimes it
opens very fast.
In apache status,I noticed this:
============================================
Current Time: Saturday, 24-Nov-2007 15:59:38 CST Restart Time: Friday,
23-Nov-2007 21:35:28 CST Parent Server Generation: 4 Server uptime: 18 hours
24 minutes 10 seconds Total accesses: 2798113 - Total Traffic: 74.8 GB CPU
Usage: u520.45 s77.28 cu0 cs0 - .902% CPU load 42.2 requests/sec -
1.2MB/second -
28.0 kB/request 150 requests currently being processed, 0 idle workers
============================================
The last line, requests,I found it always is 150.For example ,150
currently,and 0 idle,or 138 currently ,12 idle.
The cpu and memory load of my server is low, so I think the problem is the
"REQUESTS".
How can I change the max requests of my server?
I changed my prefork.c to a very large number,for example:
====================================
<IfModule prefork.c>
StartServers 100
MinSpareServers 100
MaxSpareServers 200
ServerLimit 12000
MaxClients 8000
MaxRequestsPerChild 12000
</IfModule>
====================================
it's is so large,isn't?
My Apache configuration:
====================================
[EMAIL PROTECTED] ~]# /usr/local/apache2/bin/httpd -V
