I have a small VPS and hosting several websites on it, I read that it can speed up web pages by optimizing CSS, JavaScript, images without requiring me modify your existing content, is that correct? and how to install it on my Centos with apache web server?

As I briefly read about It's can speed up web site.

To install the packages, on Debian/Ubuntu, please run the following command:

sudo dpkg -i mod-pagespeed-*.deb
sudo apt-get -f install

For CentOS/Fedora, please execute:

sudo yum install at # if you do not already have 'at' installed
sudo rpm -U mod-pagespeed-*.rpm

After installed it, I can use it immediately without any configurations?
How to check if it helped improve speed or optimize css, JavaScript, html fro my sites?

I found some articles on the internet about this but configurations for this mod are complex and I could not do as they guided.

Sorry I can't help you from here, I didn't use it and didn't read about it.
If this can help PageSpeed configuration

Or look at on some tutorials from web hosting blogs.

Maybe someone will join this discussion who know little more about it.

How You can check if mod_pagespeed works?

You can check Gtmetrix and check your caching and page speed.
First disable any other caching and check plain Website.
write or make picture of results or leave it open in one tab.
Then install and activate mod_pagespeed and check your website again (on other tab) then compare results.
See if there some suggestion what do you have to do and try to search answer for that.

After you done everything enable all other caching and check your website again and see final result.

I think LiteSpeed had mod_pagespeed built in though I couldn't find it when I checked some months ago. cPnginx has it built in though I found it to be quite buggy when it was first released, and I haven't used it since.

It's better when you optimise the website files themselves going by tips and suggestions at Google PageSpeed Insights.

only their Google PageSpeed SAAS service, not the product itself which is mod_pagespeed for apache or ngx_pagespeed for nginx
Thanks.

cPnginx has it built in though I found it to be quite buggy...
Any plugin that changes cPanel to a Nginx system has issues. I think there's only two or three plugins, and of those;

- One was the original, and I think people had issue with support
- The second one was a complete copy of the original
- The third one fell off

I tested two of them a few years ago, and beyond it being buggy, removing the plugin was another issue. One would then need to fix Apache to get it working again.

Agreed testing a few nginx cpanel plugins years ago and they weren't optimal, had to tweak their default nginx settings myself.

From when i tested mod_pagespeed for apache seems to use relatively more server resources i.e. cpu than ngx_pagespeed does with nginx. Both mod_pagespeed and ngx_pagespeed do use more resources to get that page load speed benefit though as there's no such thing as a free lunch. You need to pay for the performance i.e. memory caching for performance you pay with increased memory usage :)

mod_pagespeed is highly used with React.js websites, it makes the website super smooth and flexible however for normal JQuery and normal HTML, CSS you'll barely notice any difference

mod_pagespeed is an open-source Apache HTTP Server module that automatically applies various optimizations to web pages to improve their performance. It's designed to optimize resources like images, CSS, JavaScript, and more, leading to faster loading times for web pages. The module is developed by Google and is available for both Apache and Nginx web servers.
