Show HN: Wcp – a reimplementation of cp using io_uring. With a nice progress bar

The chart is over NFS, but the listed speeds in the blog, and on github[1] are from a copy on a local SSD. That is a bit confusing though, maybe I should make it more clear. I used the network copy for ETA calculation because it was an easy way to make the transfer take longer -.if the whole copy is only a few seconds long it's difficult to meaningfully compare ETA estimation accuracy between two approaches. I would like to have more performance data though.

  Discontinued Warp speed Data Transfer (WDT) is an embeddedable library (and command line tool) aiming to transfer data between 2 systems as fast as possible over multiple TCP paths. (by facebookarchive)

  

That's great stuff, I wonder how it compares to wdt[0] when there's only one TCP path. This has been my go-to tool to transfer files on the network.
