Both, actually.
GZip can only compress files that are hosted on your server.
If you are referencing an external script or JS (like putting a Google Map or having the Google+1 button on your site) then it will not (because nothing can) GZip those things.

Try using this, it will help you to determine exactly what is not gzipped and what is gzipped.
Violacase,
We would love to know if you had any further developments on this topic. Would you like to share your URL with us so we can take a closer look for you?

Hi ‘CustomWPNinjas’,
Today ySlow says there are ’15 plain text components that should be sent compressed’ on my personal blog.
All files are hosted on the server. To minimize the chance it has something to do with cacheing I deactivated other cacheing plugins for your convenience.
Thank you – and also, you should only using 1 caching plugin at a time. If not it runs the possibility of a conflict which means a crash with things like .htaccess.

These files, although hosted on your server, are JavaScript files and must be individually handled. More than likely, there are ugly comments, or poor structure involved in the coding.
In the GZip plugin we are directly zipping these files:
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript
I am going to continue to look at this for you, expect another answer (maybe even more educated answer) in a couple of hours.
Hé CustomWPNinjas,
You’re really working on this thing… Nice to see. I know multiple cacheing plugins working simultaneously is bad practice. (Unless you know what you’re doing)
You don’t have to hurry, it’s not of big importance for me right now. I’ll wait and see.
Happy coding!
lol, yeah, we want to support our plugins and our customers as we would want to be serviced.
We are working on it, but the two hour mark was your typical under estimate on this. I’ve found a place that minifies and gzips the jquery file to 19kb and I’m trying to figure out how to implement it in this plugin. Most are 58.9kb.
Maybe it is another plugin, maybe not. But that is the biggest issue that is striking me on the profile I saw of your website – those additional files.
Keep things static for me if you can so my scans return the same information. Let me know if you need to change something.
Oh, by the way, try a plugin called wp smush.it for your images, will make a huge difference on page load speed. You may still need to manually do some, but it is awesome (I didn’t write it)
Any update on this Violacase?
Hey Viola,
I hate to mark this as resolved, but it is painful on the ratings if I don’t.
I’ll work on this as long as you want, but I think mod_deflate is not installed on your server.
Email me any questions ninjas [at] customwpninjas.com
Hi CustomWPNinjas,
Sorry for not responding a bit sooner. I’m very busy with other stuff now. I can’t make any time for examening cacheing problems for now. I’ll send you an email when the time comes and I need support. I can fully understand you mark this thread as resolved. Happy coding!
Viola,
I’m serious – I think it is a mod_deflate error.
When you’re ready to work on this, send me an email at ninjas [at] customwpninjas.com – I want to help you.
