You didn't provide enough details about the problem you're trying to solve in order to give an informed suggestion.

What is your use-case? Are you building a CRUD application? A real-time game? A search engine? Where is your anticipated performance bottleneck? In some cases the database is the blocker and no programming language choice is going to really matter.

If you do have any legitimate performance concerns, can you solve them in some clever way? Perhaps with caching, pre-computing answers to problems, or reorganizing your UI to perform computation in the background?
