Well I took your lead and downloaded CaffeineMark3 so I could see if I
could reproduce your results. First off it is a shame that your image
results returned 0. Ok First off I ran the tests three times on the
same computer but with different jdk's, once with jdk1.2(win32),
jdk1.2v2(linux), and jdk117v3(linux). First off if you just compare
the average final results I get an average of 5306, 2418, 696
respectively. Which tells a story of for some reason Sun's jdk for
win32 is twice as fast as linux's. But that doesn't make sense for us
here with the fact that on linux, the jdk1.2v2 seems slower than
jdk117, since the 1.2 scores more than three times faster. But the
telling part is if you look at the sub-tests, 2 in particular: image,
and dialog. When testing the jdk1.2v2 I get an average of 116 for
image and 125 for dialog speed. Whereas testing the jdk117v3 I get an
average of 720, and 150. For images this is almost 5 times as slow in
jdk1.2. You can even see it, the benchmark even redraws itself
noticably slow.
I tried running the benchmark without the JIT, but I get the same
results except everything is as slow as the jdk117. Well let me know
if this is the same as everyone sees, and not my system(celeron
4.5x102mhz, 64mb ram, TNT video card, RH 6.0, jdk1.2glib2.1).
