What advantage does thread pool + io_uring have over just thread pool? Unless you have millions of CPU cores and therefore many downscaling/encoding/highlighting tasks starting/finishing every second, I still don't see what io_uring brings to the table. Running tasks in the background does NOT require io_uring.
