Hey Guys,
I have a web server running:
apache - httpd-2.2.0
php - php-5.1.2
The site that is hosted on this server has very high traffic and is on a
50mbit bandwidth:
qdisc tbf 8006: dev eth0 rate 50Mbit burst 1531b lat 48.8ms
The problem is that during peak hours (sometimes during normal hours) this
system becomes very slow and the commands take longer to execute. Also
the site becomes really slow. We have tweaked the followng httpd options:
<IfModule mpm_worker_module>
ServerLimit 80
StartServers 10
MaxClients 1995
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 35
MaxRequestsPerChild 0
</IfModule>
Also, I have made sure that HostnameLookups is Off. The following is the
server hardware info:
Dual Intel(R) Xeon(TM) CPU 2.66GHz
2GB of ram
I have added 4GB of swap space to this server as well. However, none of
these changes have improved performance. Any ideas what I might be able
to do to make this server perform better?
Any suggestions or comments would be grately appreciated.
Thanks in advance.
