This page shows results of performance comparisons among Java runtime systems on Linux. I applied the following benchmarks to many Java runtime systems. SPEC JVM98 shows scores for each benchmark program and the geometric mean of them.
Higher number is better.
However the Kaffe needs more than 32 MB as heap size. I supplied 48 MB to the Kaffe. They were collected by NIST researchers. Therefore, SOR, which shows relatively higher value, affects the composite score. Oppositely, FFT and Monte Carlo do not very much.
