Several articles have compared the Transputer to 68000s
(SUN 3s) and VAX 780s.  I had got similar results when
testing some T800s with a beta C compiler (the developer
of which shall remain nameless).  Needless to say I was
less than impressed.  About 2 months ago I got ahold of
another demo board and a Logical Systems C compiler
(from CSA).  My ray tracer, which is very cpu and
floating point intensive, ran 25 times faster than
with the other vendors C compiler.  The execution
time was equal to that of a SUN 4!

This just goes to show you that while hardware may be
the same, the compiler can make all the difference.
I would reccommend potential buyers to test as many
different compilers (C, OCCAM, whatever) before
buying.  You could be wasting a lot of compute
power.
