Using Google Chromes new Speed Tracer extension to profile my app.

Appears my app is constantly reporting "Sluggish (events) 100%", which means the browser is blocking html rendering.

I don't understand enough how to interpreter the Speed Tracer tool to fix this issue开发者_如何转开发.

Any help appreciated. My web app is: bit.ly/7J0U

Doesn't seem sluggish to me (Macbook 10.5.8/FF 3.5.5). My initial thought was to direct you to some event delegation information, but that doesn't seem applicable after visiting your app.

Try to get a barometer for Speed Tracer's reports by running the tool on different sites and see how they compare with your own. That may help you to get a better sense of how to interpret the reports. Also, don't forget that these things (YSlow included) are tools not rules.
