Subject: [jQuery] Speed Tests
In the vein of the discussion we've been having on this list (and, of
course, heavily inspired by the first speed test), I've created a more
extensive speed test that tests a bunch of similar cases.
A word of warning: your browser will not be available for a good 30
seconds or so while the test is running, but it will not lock up.
The first thing my code does is test how long it takes to run a
$(".class") query, and bases the number of attempts for each test on the
speed of that query (not a perfect system, but it should prevent crazy long
loads on slow computers.
Check the test out at:
