Performance
[Edit]
Methodology
- GP2X : clock at 200 MHz, Cacao JVM 0.96-svn-rev5274-rev254, GNU Classpath 0.92 with float fix for ARM
- PIII 700, Debian Sarge: Cacao JVM 0.96, GNU Classpath 0.92
- Benchmark used: JavaGrande sequential benchmarks
Performance ratio is given at same frequency :
- R = PERF_p3 / PERF_gp2x
