Trust me this will solution with surprise you.
Forget all the promises made by any plugin. The only caching and compression plugin I have not tested is hummingbird. My solution is superb. Try it and you will thank me for it!
We have to do this together, though, to speed up and optimize your wordpress or any other right now.
Note This is more for advanced users who are comfortable with modifying the .htaccess file, php.ini file and wp-config.
*This a secrete even Web Host giants will not disclose so easily to sell…***I am sharing with you for free. Please only one favour share this post and tell friends. Thank you.
First, you need to backup your website before making any drastic changes like this:
Step 1: Test your site on Google PageSpeed Insights, Pingdom Tools, and GTmetrix to view your current score.
Step 2:* Open up your .htaccess file located in the root directory of your website. This can be found by accessing your files via FTP. What we want to do here is enable browser caching, protect from DDoS Attacks, cdn support, etc. Once you save the changes to your file, go back to your website and make sure it’s still functioning normally.

###############################
Remember, thw above will not give you 100% pagespeed without changes in your php,ini
DO NOT FORGET INITIALIZATION FILE, Different for joomla, Drupal, WordPress, etc. For WordPress, which I use, see below and add to the .htaccess file above, preferrably at the top or [bottom] to the file stream:
BEGIN WordPress
RewriteEngine On
RewriteBase /shopfinish/
RewriteRule ^index.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /shopfinish/index.php [L]
END WordPress
Step 3: Limit the number of post revisions. By default, WordPress would store every single change you make in your pages, products, questions, and posts. This number of revisions or verions actually overpupulate the database and your website consequently becomes slow.
Locate your wp-config.php file in the root directory of the WordPress installation. Add this line of code to your file.
/Limit Post Revisions/
define( ‘WP_POST_REVISIONS’, 3);
End Post Revisions
Alternativly, you can set wordpress to not store revisions at all. You would then call your code out like this:
define( ‘WP_POST_REVISIONS’, false); but I do not like this just incase you mess up somewhere in you editing and you want to revert back.
Now the big part
Step 4: Locate your PHP.INI file. This varies depending on your host. Check your hosting control panel for a section labeled something similar to “CGI PHP Scripts”. Or just check with your specific host. You can use ftp to your root diectory and find the php.ini or creat one if missing.
When you located your php.ini file, you want to enable Gzipping. This will blow your mind.
Locate this:
Possible Values:
; On = Enabled and buffer is unlimited. (Use with caution)
; Off = Disabled
; Integer = Enables the buffer and sets its maximum size in bytes.
; Note: This directive is hardcoded to Off for the CLI SAPI
; Default Value: Off (Change this to “On”) be careful as it could cause problems if you observe any anomalies, use the production value below (4096). which is 4kb
; Development Value: 4096
; Production Value: 4096
;http://php.net/output-buffering
output_buffering = Off
Now search for the following – the most imprtant part of this work
zlib.output_compression = Off (Change this to “On”)
zlib.output_compression_level = -1 (Change this to level 6 instead of -1)*
The level “#” you currently have will more than likely be different. Set it to the number 6 as shown above. Save your file and make sure your website is still working correctly. You should be able to see an increase of speed of your website.
Step5: Retest your site on Google PageSpeed Insights https://developers.google.com/speed/pagespeed/insights to view your new score. How do they compare?
Check with GTmetrix https://gtmetrix.com/ and Pingdom Tools https://tools.pingdom.com
You can as well spend all the time you have to speed up your wedsite using CDN and CSS Sprites. They are recommended, Cloudflare, MaxCDN, KeyCDN, CDN77, Amazono Cloudfront (the one I used before switching to Cloudflare and BunnyCDN), etc,! However, until you can find that time and the expensive resource, just enabling the features I just showed you will speed up your WordPress website incredibly in less than 10 minutes of work! With no plugins at all!
Resources I used. Consider following these tutorials to better improve your website speed and optimization.
