During the discussions last night about the performance of certain sites
that shouldn't be named, I mentioned YSlow, a toolkit for suggesting
performance improvements to your web page, and Ewen said he hadn't heard
of it before.

It's a plugin for Firebug, which in turn is a plugin for Firefox; see
http://developer.yahoo.com/yslow/.

Popular local sites score for their home page:

    http://www.stuff.co.nz/ -- Grade E, 59/100
    http://www.nzherald.co.nz/ -- Grade D, 61/100
    http://trademe.co.nz/ -- Grade C, 72/100

For comparison, news.google.com gets a B with 86/100, and news.yahoo.com
gets 88/100.

Other interesting statistics; stuff has 1999 DOM elements on the home
page; Trademe has 1061.  Stuff has 7 stylesheets; Trademe has 3; Granny
has 1.  

There's lots more mocking I could do about how the various sites are
coded (why does Granny Herald feel that a complete list of regions for
their weather forecast should be coded into the text of a script block
on the homepage, instead of being served from a JS file?), but I won't.

Michael.
