This month in Servo: parallel tables and more (via) New in Servo:

Parallel table layout is now enabled (@mrobinson, #32477), spreading the work for laying out rows and their columns over all available CPU cores. This change is a great example of the strengths of Rayon and the opportunistic parallelism in Servo's layout engine.

The commit landing the change is quite short, and much of the work is done by refactoring the code to use .par_iter().enumerate().map(...) - par_iter() is the Rayon method that allows parallel iteration over a collection using multiple threads, hence multiple CPU cores.
