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.
