I know there may be no perfect objective answer for this, but did someone create benchmark like this? Or around how much different should I expect? The computer hardware is pretty good in these years, then there is not much different now? I main concern is a program that mainly purely a lot of calculation in a lot of data in array with no graphic except a very basic swing gui as control panel. If we have the same hardware and same java code for the calculation program, what difference should that be?

Why not just trying it out, if you are so interesting? There is nothing principle in this problem. Besides, you should understand that it may depends on the code in question. Some code might be faster on one Java machine than another one, but some other code could time in an opposite way. Didn't you think about it? So, your could get more useful estimate if you do it by yourself, with some code samples which you are interested in...

There would be no difference. This is because Java is the middle tier and is therefore acting as a bridge between your application and the underlying Operating System. Therefore, the only determinant to how fast your application is is not actually the underlying Operating system, but the Java platform.
