Slower than cp? #13
Description
I'm looking at possibly using io_uring for a package manager and I tried out wcp to get a sense for what the performance would look like for recursively copying files/folders via io_uring
I was surprised to see that it seems slower on Ubuntu 20.04.1 AMD64
I can confirm that this is a release build:

# This is the CMakeCache file.
