How to speed up your magento

One of the drawbacks of Magento is currently its speed if default configuration is used. There are certain ways of making it run faster. The best one is to enable GZip compression by changing .htaccess file a little. You just need to uncomment part of the code. In my case, the speed increase was exactly 235%. Let’s start speeding up Magento!

Find the following lines in your Magento .htaccess file and replace them with the following code.

############################################

## enable apache served files compression

## http://developer.yahoo.com/performance/rules.html#gzip

# Insert filter

SetOutputFilter DEFLATE

# 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 \bMSIE !no-gzip !gzip-only-text/html

# Don’t compress images

SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip dont-vary

# Make sure proxies don’t deliver the wrong content

Header append Vary User-Agent env=!dont-vary

# enable resulting html compression

php_flag zlib.output_compression on



Enable your cache by going system -> cache management -> select All

Many Magento issues are caused by slow performance. The recommended way to speed up Magento's performance is to enable its Compilation function. The performance increase is between 25%-50% on page loads.

You can enable Magento Compilation from your Magento admin panel > System > Tools > Compilation.

Combine Javascript and Combine CSS files: System ->Configuration ->Advanced ->Developer -> ‘Javascript settings’ and ‘CSS Settings’. You can also consider using an extensions to do this like the Fooman Speedster extension, whichever works best for you. 

Disable the Magento log: System -> Configuration -> Advanced -> Developer -> Log Settings (default is disabled).
