I goofed with the last message and messed up the formatting.

Hello,
We have formally evaluated the different virtual machines available
for Linux and thought it would be worthwhile to share the results with
the Linux community.
The following tests were conducted on an unloaded dual processor
Pentium II/400mhz running Debian GNU/Linux (kernel 2.2.8). Each
benchmark execution was repeated ten times. We discarded the maximum
and minimum results, and averaged the remaining 8 execution times.
The first 9 benchmarks come from the specJVM98 benchmark suite
(http://www.spec.org), and the last two benchmarks come from our own
private collection.
base(s): time in seconds to run under blackdown jdk 1.2, pre-release
2, with jit.
sunint: speedup (base time/this time) of the blackdown jdk1.2,
pre-release 2, with no jit.
borjit: speedup of blackdown jdk1.2, pre-release 2, with the Borland
jit installed (http://www.borland.com)
ibmjit: speedup of the AlphaWorks IBM 1.1.8 JIT
(http://www.alphaworks.ibm.com)
A # indicates that the run failed validity checks.
base(s) sunint borjit ibmjit
check .84 - 1.33 - 1.25 # 1.75 -
compress 65.61 - .15 - 1.07 - 2.42 -
db 148.43 - .57 - .98 - 2.98 -
jack 64.50 - .43 - 1.35 - 3.65 -
javac 75.67 - .54 - 1.21 - 2.51 -
jess 50.86 - .47 - 1.44 - 2.67 -
mpegaudio 54.61 - .15 - 1.19 # 2.32 -
mtrt 40.32 - .41 - 1.78 - 2.79 -
raytrace 55.56 - .45 - 1.92 - 3.04 -
sablecc-w 42.57 - .58 - 1.06 - 2.32 -
soot-j 132.93 - .69 - 1.25 - 2.26 -
The conclusions are fairly obvious. Now, if only IBM had a jit for
1.2... We also evaluated shujit and tyajit, but they were unable to
run most of the benchmarks correctly. Stay tuned for a comparison of
NT Java Virtual Machines in the near future, on the same hardware.
