High Speed with: C++ or GO

If modules of your application are time critical to your business processes, you might consider a programming language like C++ or GO.

As many developers point out, Go has the speed of a compiled language, but the feel of an interpreted language. So you can write the code fast, and even faster compilation speeds allow for a rapid feedback style. Speedy development means saving time and money, so this is obviously the most important benefit for someone with a tight budget.
