How to speed up websites

Posted on: July 5th, 2013 by admin No Comments


I recently implemented deflate on apache following recommendation from Google  PageSpeed Tools



Find your apache configuration httpd.conf

SSH to your server and run this command

$ ps -ef | grep apache

then run

$ /usr/sbin/apache2 -V

Find your apache configuration in my case CentOS it is located at



Enable mod_deflate by modifying httpd.conf




# mod_deflate configuration

<IfModule mod_deflate.c>
# Restrict compression to these MIME types
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/x-javascript
AddOutputFilterByType DEFLATE text/javascript
AddOutputFilterByType DEFLATE text/css

# Level of compression (Highest 9 - Lowest 1)
DeflateCompressionLevel 9

# Netscape 4.x has some problems.
BrowserMatch ^Mozilla/4 gzip-only-text/html

# Netscape 4.06-4.08 have some more problems
BrowserMatch ^Mozilla/4\.0[678] no-gzip

# MSIE masquerades as Netscape, but it is fine
BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html

<IfModule mod_headers.c>
# Make sure proxies don't deliver the wrong content
Header append Vary User-Agent env=!dont-vary




Restart Apache

/sbin/service httpd restart



Test to make sure deflate is working correctly  by going to this website and test your URL
