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.

Sometimes developers only care about speed. It’s less of an apples-to-oranges comparison and more like apples-to-orange-sherbet. Why RPC is “faster” It’s tempting to simply write a micro-benchmark test where we issue 1000 requests to a server over HTTP and then repeat the same test with asynchronous messages.
