Google "Page Speed"

So since now Google uses the loading times of a site as a variable for ranking, they released a "Page Speed" add on for FireBug that basically analyzes your site with tips on how to improve it.

Now, I just ran this tool and found a plethora of issues. Problem is, some of these are just core vBulletin things, and I am not sure how I could tweak it?

Here are just 2 (out of many more) examples:









What are your thoughts?

vB defines most of the css and js WITHOUT a cache on purpose.
ie, vb.js?v=3.8
the parameter on the url ensures it is never cached.

This ensures that your users see the correct version of your site, even if they have a cached JS, etc. This is especiallyimportant on upgrades/versions/etc.

Minifications are simply whitepsace removal or served via gzip.

Without re-coding half of vb, there's not much you can do. I doubt they will ever do these things for the usability issues and server variances for gzip, etc.
