OK, so we need a comparison between a multi threaded mmap approach and io_uring. Which would be faster?

If the memory access pattern is the same, there are no significant differences.

Just ran a version with 6 prefetching threads. I get 5.81GB/s. Same as the io_uring with 2 drives, but still a lot slower than the in memory solution.
