JAVA -> C++

<< < (2/2)

hobbes:
C++ is much faster compared to JAVA on the order of hundreds of times. It is much less forgiving but also much more powerful.

Roman505:
with great power comes great responsibility to delete()

hobbes:
yes, you have to delete what you create but at least the garbage collector does not hiccup and make your program pause.

Roman505:
with less power comes hiccoughs.

I can hate Java as much as the next guy, but this is simply not a true statement.

On modern servers and client machines, using modern Java VMs, Java is more like half the speed of native C++, when using the same level of tuning in implementation.

Even on very small form factors, where you can't afford to use JIT code generation or keep a code cache around, you can do better than 100:1, because many of the Java opcodes are more expressive than machine codes, and thus a "threaded interpreter" (nothing to do with threads of execution) can get to about 10:1 or so.

And when you are I/O bound, Java and C++ are equally I/O bound and thus equally slow :-)
