Please read also Rudi Chiarito reply.
I have made some speed measures and it is really true, that the
FPU-translation-code is really slow.
TAO had up to now no good reason to speed up the translator as Elate is was
used up to now only in embedded systems - and a x86-type CPU is much to
power-intensive to use it there... ;)

So what I think is, that - considering the current circumstances like
the unoptimized CPU-Translator, the lack of video-support and the really
roigh port of Quake - the whole stuff runs really fast!

My speed measures I made some time ago showed, that the Translator is when
calculating integer-data (not floating point!) is about 100% of the speed
than native code!
So now think of a optimized FPU-part, too... :-)

Bye
Stefan
