Measuring the speed of time Is there already a microbenchmark for os::javaTimeMillis()? As I'm interested in the relative comparison I can just compare the total runtimes (the "real" time) for the same result. Microbenchmark os::javaTimeMillis() on both systems. Try changing the kernel clocksource. How long is each time call?
