The whole point of the super pack installer is to install the most
optimized one possible on your machine. So you should not use the arch
flag (it is meant for people who want to explicity install something
which is not the most optimal one).

As for your program, it depends too much on what you are doing. Keep
in mind that java with the appropriate JVM is pretty fast,

cheers,
