Pathetic slow, not compressing

Hi,

I am using your plugin,

As per your suggestion for gzip compression i kept your code in my .htaccess.

Even though it’s not compressing please see google page speed suggestions

My .htaccess code is

<IfModule mod_deflate.c>
	<IfModule mod_filter.c>
		AddOutputFilterByType DEFLATE text/plain text/html application/x-httpd-php-source
		AddOutputFilterByType DEFLATE text/xml application/xml application/xhtml+xml application/xml-dtd
		AddOutputFilterByType DEFLATE application/rdf+xml application/rss+xml application/atom+xml image/svg+xml
		AddOutputFilterByType DEFLATE text/css text/javascript application/javascript application/x-javascript
		AddOutputFilterByType DEFLATE font/truetype application/x-font-ttf font/opentype application/x-font-otf
	</IfModule>
</IfModule>
