It's not always faster than the JVM, but I'm pretty sure you can't be comparing exactly the same algorithm here. Can you post one or all of the other implementations?

Here, i want to implement a program which displays the amical numbers couples given a limit. I'm using the very same algorithm i'm using in Python, Java, Haskell, Scala, Nim, etc.) My Go code is visible here : http://sprunge.us/bSgW When running the executable created with go build main.go on a MacBook Pro and with a limit of 1000000, the result is processed in 8,815 secs ($ time ./main 1000000) The same program written in Java gives 2.6 secs (and it counts the first load of the jvm...), Nim gives 2.5 secs, Scala gives 5 secs. Python (with pypy) gives 10 secs. I've not tried with C but i'm sure it would be even faster than the Java or Nim versions. So, given all my programs are using the same algorithm, why the Go version is so slow comparing to Java/Scala ? I was expecting Go to be faster than a language running on the jvm.
