Done! Here're the results:-

Desktop - Pentium III 1 G Hz 754 MB	->	10.x min.
Tablet PC - Crusoe TM5800 1 GHz 731 MB	->	17.x min.

 From freshdiagnos benchmack, the TPC has about 2x faster RAM.
I use tmpfs for the whole process so disk speed didn't count.
Both test run without X or any foreground process using
2.4.21-ac1 and RedHat kernel.

What do you think?
Shouldn't TM5800 with 4-wide VLIW engine and 64 registers,
working on a single task, run as fast as a Pentium III?
Why it take 70% longer for such small process (make+gcc+as)!
There must be something wrong.
