Article more or less: "I don't think that we do, so I tested it a bit. Tests confirm my assumptions. Still; there are cases where 32 bit is faster. I won't bother to explain why." As usual "All headlines that ask a question can be answered no" ( but inverted to make it more confusing ). Really the title of the article to fit the mold should be "Can we get rid of the 32-bit JVM?" Really what should be done is take the algorithms from language competition website, and then test all of those on 32-bit versus 64-bit with different data sets. A few tests is hardly conclusive or explanative of what is fast and what is slow. Obviously a raw call to nanotime will be slow. Do you really need nanotime? If you don't; is a lower precision call faster than nanotime?
