From my original understanding of
asyncruntimes I thought you could slap anasyncon anything you expect to take some time to complete. After further reading, I don't think this is the correct approach for CPU-bound work that does not benefit from concurrency (unless by use of multiple threads but that is besides the point here). The additional context switching of adding a future that may or may not poll as ready might even add some overhead. Here I remove theasyncfrom CPU-bound functions to remove any unnecessary context switching.Happy to let this one marinate for a little if there is some interest in actually profiling if this does anything. Although I don't think there will be any noticeable effect, I think it is good practice to remove the
asyncfrom these functions.ref: https://users.rust-lang.org/t/should-you-only-use-futures-for-i-o-bound-tasks/100784
