Yeah I think if you want performance, the more important thing to do from the start is focus on loose coupling and separation of concerns. The idea is that when you do want to optimize performance, you want it to be easy to isolate critical sections, measure them, and make improvements. Premature optimization is just going to make progress slower, and you might not know what bottlenecks you will end up creating until the project is farther along. There are also some basic things you can keep in mind from the start: like if you need predictable performance then you should avoid choosing a language with stop-the-world garbage collection.
