Thank you for that summary, Jake! And for the stat lesson. :)

Since the 7th click is reproducible, and has little to do with the
issue, you can discard the value, with a simple note... years of
stat classes!
conclusions:
running thru the whole dom looking for a class is slow.
looking for an ID (which should be unique) after getting the tags
is worthless.
looking for a class after getting a subset of the dom is faster
than searching the whole dom.
Safari is almost always faster than ff!
Just what was expected!
GREAT WORK!

Hey everyone,
I have results of a few more speed tests that I ran this evening at
http://test.learningjquery.com/speed-test.htm
Method: I clicked 10 times on each query in Firefox 2.0 and Safari
2.0.4 (See HTML source for all code, markup, etc.) I recorded the
mode (most common value) and the range of values for each, all in
milliseconds.
@ FF2 / Safari2
1. $('#speech28')
- mode: 1 / 1
- range: 0-1 / 0-4
2. $('div#speech28')
- mode: 43 / 32
- range: 42-59 / 30-35
3. $('#final-speech div.final-dialog ')
- mode: 5ms / 5ms
- range: 4-6 / 3-6
4. $('#final-speech .final-dialog')
- mode: 6 / 5
- range: 5-8 / 3-6
5. $('div.final-dialog')
- mode: 55 / 40
- range: 28-253 / 40-45
6. $('.final-dialog')
- mode: 101 / 51
- range: 83-306 / 51-68
***
Note that queries 5 and 6 have huge ranges in Firefox because of
the mysterious seventh click issue.
Looks like these tests confirm what we've all been saying on this
list about the relative speed of various selectors.
This has been a fascinating exercise. I'd love to hear people's
analysis, etc.
