Hi everyone...

I'm working in a project that uses C++ and I want to get the best performance possible. My software code should be platform independent, so I can run it in any OS.
Today, I am compiling the project only for 32 bit machines, forcing the OS of 64 bit machines to translate the compiled instructions.

My question is: This approach I've chosen (compile only in 32 bit) impacts the performance negatively if I run it in a 64 bit machine? Is so, would it be slower than a 32 bit machine (completely equivalent machine, but 32 bit), or it would have the same speed?


Thanks in advance for your attention
