Apache provides an option to control gzip compression level:
http://httpd.apache.org/docs/2.0/mod/mod_deflate.html#deflatecompressionlevel
DeflateCompressionLevel 1 (fastest compression) - 9 (best compression) -
default is 6.
I think we could add a test to check if resources are gzip using highest
possible level. Believe or not, but someone in my team changed the config to 1
and this issue existed not noticed for around 2 years!
The different for an example javascript file minified using yui is:
478969 original.js
182607 original.js-fast.gz
157171 original.js-6.gz
156894 original.js-best.gz
So the diff between 6 and 9 is not much (277b, 0.2%), the diff between 1 and 9
is significant (25k, 14%).
