wcp VS hacn

Not a question, but I made a similar tool in c++[1], for Linux only using io_uring, and a blog post explaining its internals [2]. I'll definitely have a look some time soon, I'd be interested to see how performance compares (I gathered from some other comments here that you're using blocking io in threads?)

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.

Unix cp, but with a proper progress bar, and much faster:

Getting close now but not ready for real use. io_uring is awesome.

https://github.com/pj/hacn - kind of like a react monad written in F# using computation expressions. I'm slowly doing a rewrite of parts of it because it isn't very good.

Hacn: https://github.com/pj/hacn. It’s kind of like a React “monad” in F#/Fable using computation expressions. Control flow is a bit different, basically operations/effects can trigger re-execution of subsequent steps. Right now its alpha quality and any feedback is welcome.

Currently working on Hacn, which is kind of like a React ‘monad’ or DSL using computation expressions in Fable/Feliz.
