Can someone explain why this is better than a real profiler, or something like YSlow?
I'm not criticizing - just trying to figure out what I'm missing.
I'm interested too if its better or worse... I just made it to be browser/platform agnostic.
If you're using an analytics package that let's you send custom events, you could use something like this to find out how your page performs in the wild. With things like YSlow, you're only getting data for your location and your browser.
