Holy crap people give it a rest. It's really not a big deal. We're only talking a few threads here. If you're really that worried, chances are you already have crappy performance to begin with.

The extra threads will not hurt performance as the lowest priority flag is set. There is no need to introduce extra code and make things more complicated.

I'm curious why they don't just query the number of CPU cores and set the number of threads accordingly. It can't be that complicated if Python makes it as simple as multiprocessing.cpu_count().

The threads are set to minimum priority so for those not running at least quad-core processors the negative impact is hopefully minimal.

Mesa's Disk Cache Code Now Better Caters To 4+ Core Systems
Phoronix: Mesa's Disk Cache Code Now Better Caters To 4+ Core Systems
Most Linux gamers these days should be running at least quad-core systems so Mesa 19.3 has been updated to reflect that reality with the number of CPU threads used by their disk cache...
