When viewing the URL
(http://www.devx.com/free/hotlinks/2001/pointcounter102401/pointcounter_CPvsRJ.asp)
the browser becomes extremely slow - the cpu meter jumps to 100% for quite a few
seconds and the disk starts spinning (500MHz PIII, 128MB RAM system) - the
browser memory usage jumps from around 24MB to 32MB which does not seem
outrageous given the images in the source file, so I do not understand why there
is so much disk activity (only a few other apps are active).
Basically the html retrieved from the given url consists of a large background
image (1800x694 pixels with 8 bit color depth), and multiple levels of table
within tables with two scrolable DIVs at the innermost level. When scrolling the
contents in the DIVs the rendering is also extremely slow (and the cpu meter is
running at 100%).
Removing the multiple layers of embedded tables etc. does not affect performance
(the simple html/javascript given below will recreate the problem). Removing the
background image makes the page rendering run smoothly [but off course its not
the desires output :-)]
