It is incredibly fast! Thanks a lot for this great tool!
That has certainly been my experience in the past when experimenting with this sort of thing, that more threads makes a lot of difference.
I did. You are right, multi-threading does not give a linear speed up, but it makes fd about a factor of three faster on my machine (8 virtual cores). With `--threads 1`, fd is on-par with 'find -iname', but still faster than 'find -iregex'.
