Rajkumar - Here is a tip - sending a direct email to solicit hand-holding
or consulting is bad form on a public list such as this one, especially
when you started with a public thread.
The answer is no to both, either way. To configure event, it's a simple
matter of tweaking the following directives:
StartServers
MinSpareThreads
MaxSpareThreads
ThreadsPerChild
MaxRequestWorkers
MaxConnectionsPerChild
Your distro should have sane albeit conservative values for those which
should suit your workload, resulting in httpd using no more than 30-40MB in
total.
The next step is to configure your php-fpm pools, then use mod_proxy_fcgi
to send the php requests to it, as per the wiki article I linked before.
For help with php-fpm, you will need to ask php forums.
