In this chapter, we saw how our sequential algorithms can easily gain performance by running in parallel. This parallelism can be obtained in multiple ways, and in this chapter, we learned about multithreading. We saw how multithreading is really safe in Rust, and how we can take advantage of the crate ecosystem to improve our performance even more.

We learned about some performance enhancements we can develop for our multithreaded code, and how to use all the available tools to our advantage. You can now develop a high-performance concurrent application in Rust using multiple threads.

In the next chapter, we will look at asynchronous programming. The primitives we will look at enable us to write concurrent programs that won't lock our threads if we are waiting for some computation, without even requiring us to spawn new threads!
