[users@httpd] Configuration for high concurrent load
Good day,
I am trying to configure my Apache HTTPd server to handle 7k concurrent
requests (preferably 10k), but I cannot seem to make it work.
Does anybody have an idea how to configure for such load?
Details of my problem is in serverfault :

Thanks,

Switch to mpm_event. My config is not setup for c10k, but should top out
MUCH higher then your current config.
Apache's error messages for load are pretty self explanatory, it should
be easy to adjust the limits after you max this config.
<IfModule mpm_event_module>
MaxMemFree 10240
StartServers 2
MinSpareThreads 10
MaxSpareThreads 30
ThreadsPerChild 25
ThreadLimit 45
MaxClients 200
MaxRequestsPerChild 1000
GracefulShutDownTimeout 40
</IfModule>

Correcting typo-error
Dear Nick
Can you be bit precise here.., I am bit new to system.
What I need to do so that, one client per server would not be required.
Best Regards

The prefork MPM limits you to one client per server. Not useful for
higher loads.
Has something happened to the performance tuning section in the docs?

I am doing a similar job..
Here is the warning...
Starting httpd: WARNING: MaxClients of 7500 exceeds ServerLimit value of
330 servers,
lowering MaxClients to 330. To increase, please see the ServerLimit
directive.
So, is it the reason that can cause this issue.....
