Today I discovered a cool plugin for Firefox: YSlow.
In combination with Firebug, it allows you to quickly get a report about performance issues with your site, like too many css or javascript files, missing cache headers and much more.
I got a score of 66 for koopjeszoeker.be! Not much to improve there, besides switching to a CDN, but I don’t think this is something that will happen very soon (maybe with Amazon S3?).
Pretty cool, where did you hear about that ?
I will try it on my project too, can’t wait to see the result !
