I am trying to tune my apache CPanel VPS for faster performance.
Sometimes in peak hours, it takes too long to even load a plain HTML page, which is not using PHP or mysql at all.
PHP scripts are also not taking over 1 second, very rarely one PHP script takes 2 seconds.
Still, sometimes apache becomes too slow in responding.
Can someone please explain how these settings will affect server performance?
My server info says that I got 3 CPU on my VPS. 2000 MHZ per CPU.
TimeOut 300
I changed to 60
Is this the value which PHP overwrites with its set_time_limit() setting?
maxKeepAliveRequest 100
I changed to 30
I don't load too many extra things when a webpage is loaded. 2-5 images, and 1 js file may be.
keepAliveTimeout 5
I changed to 3.
I think this keeps a connection open between browser and server per http load. Once browser stops requesting images/css/js etc, then this comes into effect, right? So once browser stops requesting images/css etc, then apache will wait 3 seconds and will terminate connection, right?
maxConnectionsPerChild 10,000 (10k)
Not sure what this does.
I think its max number of requests that 1 httpd process can process, right?
Should I increase this to 20,000 or is it ok?
What is the difference in same httpd process keeping on handling request after request, instead of starting new process after 10k requests are processed?
maxRequestWorkers 150
I changed to 300
Is this the max number of humans/bots opening http connection to my website? This is for 1 second or how long?
If I can increase this (on a 3 CPU VPS), then how high can I go safely?
serverLimit 256
I changed to 512
Maximum spare servers 10
Minimum is 5
Start servers is also 5
Again, no idea what these are doing...
Should I increase these or decrease these?
I would greatly appreciate if someone could tell me how these settings affect server performance.
I don't want to use small settings in these and waste idol server resources.
Many Thanks
