I confused with the K6-II I used when I was a kid :)

are you saying having tried a Linux distribution 15 years younger than
your 486... with busybox/uclibc or Slackware 4.0 the performance would
probably have been better ;)

Not in mine either, such a machine is just "a little slow to use KDE4".
Especially with a Full HD panel and KWin effects automatically
activated ;)
Actually I still have a machine that I could use for KDE4/Trinity
optimisation (if I have the time to set up a cross-compiling
environment), it's not old (actually it's still in sale today) but has
a single-core non-x86 CPU and a very weak GPU which do a good job to
slaughter the Debian Squeeze's KDE4 performance.

It is not TDE code yet, but KDE4 code that could be imported into TDE
(or alternatively I could implement my own MMX intrisics code...)
