If you’re running Magento on OpenSuse (or any platform for that matter), you can really benefit from turning on http compression, especially to remote areas or from hosts that have limited bandwidth.

There are a lot of references out there on this, but you have to sort of pull it all together on your own for this particular combination.

Verify that mod_deflate has been installed in Apache:

1. Open /etc/sysconfig/apache2.

2. Find the line that starts:


3. Verify that “deflate” is one of the modules listed (may not be in alphabetical order).

Now, enable compression in the virtual host file for your site:

1. Open /etc/apache2/vhosts.d/.conf.

2. Add the following lines inside the tag:

DeflateBufferSize 32768
DeflateCompressionLevel 5

	SetOutputFilter DEFLATE
	BrowserMatch ^Mozilla/4 gzip-only-text/html
	BrowserMatch ^Mozilla/4.0[678] no-gzip
	BrowserMatch bMSIE !no-gzip !gzip-only-text/html
	SetEnvIfNoCase Request_URI .(?:gif|jpe?g|png|tiff)$ no-gzip dont-vary
	# Header append Vary User-Agent env=!dont-vary

Now restart Apache using:

sudo /etc/init.d/apache2 restart

and you should be in business!
