MySpace open sources advanced browser performance tool for IE

Category: Browsers, IE, Performance

<p>Developers tend to tease MySpace for its look, but the insiders are incredibly impressed by some of the engineering behind the scenes (e.g. their internal monitoring tools are said to be second to none).

They have surprised us again with their new tool MSFast which is “a browser plugin that help developers to improve their code performance by capturing and measuring possible bottlenecks on their web pages.”

The IE 8 tools are getting better, but in general no one has been able to touch Firebug (and the new WebKit Inspector improvements) but this tool is actually plugin for IE! It captures a lot:

  • Measure the CPU hit and memory footprint of your pages as they render on the client’s browser
  • Review screen shots of the page while it renders
  • Review the rendered HTML on each point of the page’s lifecycle
  • Measure and show estimates of the time it takes to render each section of the page in different connection speeds
  • Validate the content of your page against a set of proven “best practice” rules of web development
    Review downloaded files and show download time estimation on different bandwidths

That is some impressive data, and great to be able to test on IE where it has been SO hard to do so in the past.

I love it. I really love the rendered outputs

It is also surprising to see that the code is hosted on Google Code rather than CodePlex.

Great tool! Finally for IE something like that.

“and great to be able to test on IE where it has been SO hard to do so in the past.”

Fiddler has been available to inspect IE HTTP traffic for at least several years now ( http://www.fiddler2.com/fiddler2/ ) and ( http://www.fiddler2.com/fiddler2/images/sshot-1.png [screenshot] )

The Myspace tool looks pretty cool too. Nice, easy UI

Does anyone else see the irony in a company whose webpages are so bloated with animated gifs, embedded 20 Things about Me questionaires, and Dancing Smilies that they can overwhelm and crash a web browser in seconds releasing a browser performance tool?

@drlongghost, who would have more incentive?

No way.

It’s not bad — was wanting a little profiler like this for IE6.

Great stuff, *tips hat at MySpace*

Anyone having problems getting this to work? I click the green “test current page” icon, but I get a “test is already running on a different page”, even though there is no other page or “unexpected error”. I quit/relaunch my IE instance, try random sites, same result.

Running IE8 under Vista.

UI can be improved.
