This applet runs the last version of the Java Microbenchmarks . Each of the microbenchmarks is run three times for one second at a time, and the maximum number of operations completed within a second is used to calculate the time per operation. For an analysis of the results for a range of Java implementations on a single machine, see Java Microbenchmarks .
Lower times are better.
I've separated the results into x86 and non-x86 architectures, grouped results for similar platforms, and put them in rough order of speed. NS 4.0b1 Pentium 60 MHz 0.069 0.020 0.
