Question

I am working on a C# application that works with an array. It walks through it (meaning that at one time only a narrow part of the array is used). I am considering adding threads in it to make it perform faster (it runs on a dualcore computer). The problem is that I do not know if it would actually help, because threads cost something and this cost could easily be more than the parallel gain… So how do I determine if threading would help?

Answer 1

Try writing some benchmarks that mimic, as closely as possible, the real-world conditions in which your software will actually be used.

Test and time the single-threaded version. Test and time the multi-threaded version. Compare the two sets of results.
