SERVER OPTIMIZATION

 Apache is one of the most utilized web servers in facilitating organizations, upgrading it so it expends little CPU and memory can be fairly repetitive, for this we will make reference to two key boundaries to enhance the exhibition of apache 

Read More: linux administrator job description

KeepAliveTimeout: Regulates the time the server keeps the association open while sitting tight for additional solicitations. 

The estimation of KeepAliveTimeout as a matter of course is 15 , accordingly every association holds up 15 seconds on the off chance that the program requests something different. In the event that your pages load in under 15 seconds, you have a cycle pausing and consuming memory without taking any kind of action. 

blockquote KeepAliveTimeout 5 

MaxRequestsPerChild 

This boundary directs the most extreme number of solicitations that every youngster cycle will serve. Its default esteem is 0, it implies that every youngster will serve boundless solicitations, however it isn't suggested on servers with numerous visits, since these could make the server crash. 

blockquote MaxRequestsPerChild 1000 

In this manner, every kid will serve a restriction of a thousand demands, and will leave the rod to another kid cycle. 

Different suggestions for a decent working of apache would be: 

Burden just essential modules 

Utilize the suitable multiprocessing modules 

In apache there are 2 variants of multi preparing, 

laborer: It works at an a lot better and adaptability than the prefork, each cycle that produces a few kid measures, these are assembled and permit a similar association with be utilized, this against yet aims that on the off chance that one of the kid measures falls flat, the whole parent measure fizzles , 

prefork. keeps this cycle from fizzling, yet is more slow since every youngster cycle produces an association. 

Separate dynamic and static substance 

It isn't the equivalent to serve a HTML page than one with PHP, so through HTTP intermediaries we can tell apache that we have on port 80 to send demands for certain substance to another Apache server that is just liable for serving pictures, records or static pages. A server that offers dynamic substance can devour 20M per measure, while a static one and no more 1M. 

We can do this through the mod_proxy and rewrite_module modules 

HostnameLookups, in the event that we needn't bother with this boundary to Off and hence we abstain from sitting tight for the goal of names, with the heap this creates. 

Try not to utilize .htaccess, (AllowOverride None), yet in each solicitation Apache will watch that document and that is burden and time. 

Permit symlinks, however in each solicitation Apache will produce another to check if the record is a symlink. 

On the off chance that we needn't bother with the insights (ExtendedStatus), they can be crippled. 

Use mod_gzip/mod_deflate to spare transfer speed.
