Pinned topic HTTP Server MaxClients

‏2012-11-13T05:27:39Z |
Hello
According to

www-01.ibm.com/support/docview.wss?uid=s...

if the value of MaxClient is beyond 2000 we should add other http servers, I search the net but I could not find the reason for this limit. I want to know if I had a poweful computer with enough RAM and CPU,Could I set MaxClient to a high value (for example 6000) and I don't encounter with performance degradation?

Thanks

    Link not showing. Of course you can go higher, but you'll see some overhead/degradation. Try it and see how it works on your system/workload.

    Sorry, the link is http://www-01.ibm.com/support/docview.wss?uid=swg21167658
    We set maxClient to 6000 but when the number of busy threads (which is shown in mpm_status)goes beyond 2000, Even though the server has 4 GB free RAM and cpu usage is below 50% the web server slows considerably. We want to know what causes this behavior? Is there any OS limitation or overhead which cause this?
    Thanks

    Could be scheduling overhead. You could try more threadsperchild (or less, depending on what else you changed) to see if it provides any relief.
