  This is a PPRO/200 w/32M of memory, a machine people can pretty easily
afford ($3k).  I also use a 586/100 laptop, which damn near anyone can
afford ($1500 5 months ago)

  Something is wrong with your installation of Emacs/W3.  Drawing phase
takes 39 seconds on this machine.  The table is what kills you on that
page, and there is no way around that, if you want to get them right.

  The only reason they are that fast is because their parser pretty much
sucks, throws away structure, etc.  Real streaming parsing won't be
feasible until people go to XML, which tells you right off whether a tag is
going to be terminated or not.
