It depends on the size of the file, of course. For copying your 90 line .bashrc, probably not noticeable in the noise. For copying an 800GB database? Um, yea

I see this project's main value in turning loose the power of multiple cores on a filesystem full of manifold directories, backed by flash based storage that only runs optimally at queue depth >1 (which is most of them). On spinning rust this will probably just thrash the heads.
Hmmm. I wonder how 2 or 3 threads perform with zfs and a reasonable sized ARC?
- nurettin 7mo ago800gb database is still a single file, if it only threads on file level, you shouldn't see a difference.
- i_think_so 7mo agoWe definitely need more information. 9 or 10 years ago, under Solaris/Sparc with 1000BaseT connections, things were quite different than even the most boring and average Linux environment today. This discussion should drive home the importance of not listening to conventional wisdom and presuming optimal performance without actually testing your options. And particularly, don't presume that a blog post (or an LLM that scraped it) knows what's right for your particular use case.
