Does anyone know how to time how long it takes a browser to load a page? Specifically, I would like to see the difference between a page with widths defined for all of its TABLE and TD tags versus the time it takes a browser to interpret the same page without them defined. The page is about 90K - all tables, data, and no images. Do you know if the widths make a significant difference for the browser?
thanks for your thoughts.

Well, take a look at the file size of both pages--the heavier one, and the slimmed down one, and do the maths to find out how much smaller the one is than the other, and then apply that same ratio to load time.
Data is data is data. The browser will wait to display the page until the entire file is loaded. So the smaller the file, the faster it will appear. How MUCH faster is simple maths.
From http://webdev.loyola.edu/loadtimes.html
For a file size of 1000 K (or 1 MB)
14.4 K modem:13 min
28.8 K modem: 8 min
33.6 K modem: 6.5 min
56 K modem: 4.5 min
64 K ISDN: 3 min
128 K ISDN: 15.1 sec
640 K DSL: 15.1 sec
T1: 7.2 sec
All times are calculated estimates and the actual download time may vary.
To obtain the download time for any file, multiply the size of the file in MB by the estimated times
for your type of connection.
