Thankfully, I am not supporting PHP on my systems.
You are correct apachectl reports “Server version: Apache/2.4.6 (Red Hat Enterprise Linux)” Of course with the way Red Hat does backports of fixes that is not completely correct. Darryl Baker PMOET -DAPS X76674 From: Rose, John B [mailto:jbrose@xxxxxxx] I think that is Apache 2.4.6 If using PHP-FPM I think you may need to coordinate some settings in PHP-FPM (pm.max_children, etc.) with your config settings (MaxRequestWorkers, etc) in Apache. If you do rewrites you may want to be aware of this … https://bz.apache.org/bugzilla/show_bug.cgi?id=53929 From: Darryl Philip Baker <darryl.baker@xxxxxxxxxxxxxxxx> I forgot to mention, just in case this has any effect on the numbers, the OS is RHEL7 using the distributed version of Apache HTTPD. Darryl Baker PMOET -DAPS X76674 From: Darryl Philip Baker I am converting an older system Apache 2.2 using mpm_prefork to Apache 2.4. I think we would have better performance with mpm_worker or possibly mpm_event. My problem is trying to figure out what is the best ratio of threads per process,
the correct way to set that value, and the best value for the total number of threads which I think is set by MaxRequestWorkers. I am tuning my cluster of systems for a sudden heavy load of page requests but not a lot of CGI or other complex operations. These
are dual processor VM systems. Any suggestions or pointers? Darryl Baker Sr. System Administrator Distributed Application Platform Services Project Management Office and Enabling Technologies Northwestern |
