This is just a general question. I was wondering how you can make programs compile and run quicker? Does it have to do with the primative type you use or what?

hello everyone,
I once did this with the awt class in which i developed a small program in C++ and an exact clone of it in Java (functionality wise). I also developed another program in C++ to act as a benchmark thus testing seeing how fast each program responds to anything.
All the java functions were done in different threads including its click events
It seems that the Java is faster than C++ ranging from 330ms-390ms for all functionalities.
This was done years ago.........
I don't even know where the C++ benchmark program or it source codes are anymore
I am not sure about swing as i only tested for awt
Yours Sincerely

I found the link for performance improvement.

Really the best way to speed up your program's compile time is simply getting a faster compute machine. I don't really see the point in inproving the compile time as you are not taking hours to compile are you?
For the run time improvements, you should have a good grasp on how java works. This mostly comes through common sense, a solid computer science background, and experience.
There are many tools you could use: profilers, memory leak checkers, etc. If you are developing for the enterprise, Wily is a good tool I've used before: http://www.wilytech.com/
Ah and also, a good site I like to look at for reference on Java performance tuning is of course: http://www.javaperformancetuning.com/

freesoft: It seems highly likely that your test was flawed. spawning new threads for every gui action is generally a bad idea.
There are many factors that could have caused the performance you saw. You say you wrote the same functionality in the two programs---that doesn't say much. A sloppily written Java program is just as bad as a sloppily written C++ program. It doesn't sound like you created the same program in C++ and java.
That said, I believe that for most programs written with care in C++ and Java, you should expect roughly the same performance.
