Server has Gzip enabled, but Speed Tracer is not detecting it

Is there a correct type of Gzip?

Hello,

Since the launch of Google Caffeine, I've lost 20% of my visitors in 2 months. I've read and watch some Matt Cutt's interviews about Speed being a future variable to take in mind in SERPs.

I went to Google-Code-site and used the Speed Tracer Tools (Firefox and Chrome). One of the red alerts I got when testing my site was that my server had no Gzip enabled.

I contacted my tech support, and told them to enable it. They responded that the server was already enabled with mod_deflate for apache versions 2.x:

Tech support gave me an URL to verify if I have Gzip enabled, and it was positive.

But still, Speed Tracer throws this message:
"Enable gzip compression:
Compressing the following resources with gzip could reduce their transfer size by about two thirds".

Is there a "correct" type of Gzip compression? One that Google prefers?

Weird. Speed Tracer doesn't show me Gzip as red flag, but as orange flag (maybe a change in the server? Maybe techsupport modified something.

Still, it is flagged because the css and js files are not gzipped. I will research about that.

tell your tech support guys to add those other file types to the compression scheme.

if you have access to cPanel, you can do it yourself - look for the "Optimize Website" under the section called "Software / Services", usually near the very bottom of cPanel's interface.

add these MIME types:
text/html text/plain text/xml text/css text/javascript application/javascript application/x-javascript
