What is faster- Java or C# (or good old C)? [closed]

Answer 1

Writing in one language or another will only give you small speed ups for a large amount of work. To really speed things up you might want to look at the following:

1. Buying the latest fastest Hardware.
2. Moving from 32 bit operating system to 64 bit.
3. Grid computing.
4. CUDA / OpenCL.
5. Using compiler optimisation like vectorization.
