Thanks for all your answers...
After further investigations, i've got the same conclusion: the culprit is int64 and, more specifically, the mod operation. Java is faster because its ints are 32 bits. Changing all int with int32 in my code gives 3.2secs, which seems more reasonnable. So, is there a quick workaround to, say, configure the int type to use int32 instead of int64 ? -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
