Using Gzip/Deflate with Codeigniter for better performance

Question

I'm using Codeigniter a PHP framework and apache2.
I have enabled Gzip and deflate mod in apache2 and its showing phpinfo(). When I run Yslow it shows "Grade F on Compress components with gzip".
Even I changed the config.php of Codeigniter
$config['compress_output'] = TRUE;

but there is no effect. Is any thing I'm missing.

same question ? http://stackoverflow.com/questions/973969/yslow-gives-f-grade-to-files-compressed-with-mod-deflate — ajreal, Nov 11 '10 at 07:46
The above problem was coming due to proxy. In my case i don't have any proxy. — Mukesh Yadav, Nov 12 '10 at 06:05

you should enable mod_deflate just for CSS, html, js.

Ex:

<ifmodule deflate_module>
    DeflateCompressionLevel 1
    DeflateBufferSize 8096
    DeflateMemLevel 8
    DeflateWindowSize 8

    AddOutputFilterByType DEFLATE text/css
    AddOutputFilterByType DEFLATE text/html
    AddOutputFilterByType DEFLATE text/plain
    AddOutputFilterByType DEFLATE text/xml
</ifmodule>

Because images or videos are already compressed and also they take a lot of time to try to compress. Also there is a compress option on php.ini

Maybe it helps...
