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:
jarred@jarred-desktop ◰³ base ~/B/wcp build cat CMakeCache.txt (base) Fri 10 Dec 2021 12:41:51 AM UTC
# This is the CMakeCache file.
# For build in directory: /home/jarred/Build/wcp/build
# It was generated by CMake: /home/jarred/miniconda/bin/cmake
# You can edit this file to change values found and used by cmake.
# If you do not want to change any of the values, simply exit the editor.
# If you do want to change a value, simply edit, save, and exit the editor.
# The syntax for the file is as follows:
# KEY:TYPE=VALUE
# KEY is the name of a variable in the cache.
# TYPE is a hint to GUIs for the type of VALUE, DO NOT EDIT TYPE!.
# VALUE is the current value for the KEY.
