    Phoronix: Btrfs Seeing Some Nice Performance Improvements For Linux 5.9

    With more eyes on Btrfs given the file-system is set to become the default for Fedora 33 desktop spins, there are some interesting performance optimizations coming to Btrfs with the in-development Linux 5.9 kernel...

    But of course, we rely on Michael for more realistic performance measurements

      AFAICT this speedup is for doing fsync on a file accessed by lots of threads... so it is only relevant in very specialised use cases. Every progress is good, though.

        It sounds like btrfs is going to get a lot more care and attention from devs now that Fedora is on board. Does Linus still use Fedora? Maybe this will help.

          there is a reason I am using btrfs as my default filesystem of choice since a couple of years already ;-) https://www.youtube.com/watch?v=wqxz_-OGQqE

            Benchmarks, please!

              Nice to see BTRFS buttering up for some smooth storage action... that being said I do have a couple of things on my wishlist...

              Per subvolume mount options and I hope they at some point will implement disk groups and the ability to assign subvolumes to it. That would make it possible to do advanced optimizations (ssd's vs hdd's for example) and would also help take care of controller locality etc. which is very important if you do large pools.
              On my fileserver I got 24 disk over 3 controllers + the motherboard and while controller failure is admittedly rare I would like to isolate as much as possible.

                why haven't they fixed raid already?

                  you mean for benchmarking speed of filesystem resize?
