I think this started around 0309 or 0312 build.
2001031608 and 0314 builds show this problem for sure.
When I have more than three windows loading web pages, meaning the throbber is
turning for those windows, it takes minutes before I get anything displayed for
any of the windows. Once one of the window finishes loading, other windows load
almost immediately.
I am on LAN network, and those pages being loaded are not particularly slow
sites themselves:they load pretty quickly if opened one by one.
If you try to load five or six windows at the same time, it seems to take
forever, and even if I close all the windows at that point and open a new
window, you can not get back fast loading.
It looks like the memory space for MacOS is near its limit when this slowdown
I suspect that there is something wrong with the communication to Open Transport.

The only mac only change would be a fix for bug 29338.  On 3/12, the mac PR_Poll
was modified for bug 29338 "PR_Poll should not poll (spin) on Mac"

While it's lots of fun to pass this bug around like a hot potato, has anyone here 
actually seen this slow down on their Mac?  Running 3 jrgm page-load tests in 
three different windows, and browsing cnn, bbc, usa-today in a fourth, I didn't 
see more than the expected slow down from trying to make my 400 MHz G3 do the 
unusual.  The updating of the windows wasn't as interleaved as I expected, but 
hyatt might have a better idea of why that would be.

I got CodeWarrior and Perl up as well, but there is still some memory left.  
Doug, Simon, Patrick, what have you guys tried so far?

It is WFM in recent builds. I can not be specific, but this has not happened
since in the past week's builds.
