    Phoronix: NixOS Takes Action After 1.2GB/s ZFS Encryption Speed Drops To 200MB/s With Linux 5.0+

    The change in Linux 5.0 that initially broke ZFS On Linux compatibility ends up being pretty nasty for the ZFS encryption performance... A NixOS developer reports that the functions no longer exported by Linux 5.0+ and previously used by ZoL for AVX/AES-NI support end up dropping the ZFS data-set encryption performance to 200MB/s where as pre-5.0 kernels ran around 1.2GB/s...

    Why don't we just have an "offshore fork" where we ignore all IP annoyances and do what is best for the codebase?

    Have any other distros besides NixOS picked up this patch?

    Just wondering if Canonical will include this tiny patch on Ubuntu 19.10... Any ideas?

    Feels like a deja vu.. BTRfs was supposed to kill off every other file system too.
    10 years later..

    Would you happen to know if it has GRUB issues from time to time? Similar to ZFS/BTRFS compression.
    I don't think you'll have any issues with GRUB for the simple reason that GRUB doesn't support it at all, which means you'll have to have a /boot partition to boot to bcachefs. Fedora, which I use, creates a separate /boot parition even for supported filesystems.

    Still, I wouldn't trust this FS with any critical data yet. I bet this FS doesn't have more than a dozen regular users which means it hasn't received enough testing yet. Only after it's been merged with mainline and has been there for at least three releases, only then I'd put my data on it.

    It can replace all of ext4, ZFS, Btrfs, XFS and JFS.

You are out of luck with programmable gaming peripherals, most PCI Express video capture cards (at least OBS Studio is open software) and have major head ache in the form of driver breakage following updates.

    Afterburner does lots of things at the same time. Starting from regulating GPU fans according to temperature, ending with a FPS/CPU/MEM overlays on your screen. Add in everything in between like recording videos, taking screenshots, overclocking GPU and so forth. In order to replace it, you'd need about dozen different utilities.
    Now, tell me the probability that you'd run into some sort of issues with just one (if not more) of the replacement utilities? I'd say it's close to infinity.

    Imagine you set painstakingly everything up. You have about 15 different utilities properly configured. Even manage to game some days. Then system update happens - and you'd spend next 2x24h trying to figure bunch of issues - starting from f-ed up graphics driver to some segfaulting gaming utility. Joy, isn't it? 2 such incidents later, you'll give up and install windows.

    Enough of OT now
    Are you really going with that retarded controller argument? If you were a real "enthusiast gamer" you'd know that different controllers are better in different scenarios. "Enthusiast gamers" know to use flight sticks with flying games, arcade sticks with fighting games, wheels with racing games, console controllers with side-scrollers/JRPGs/emulators, keyboard/mouse with FPS & strategy games...or just play with what makes you feel comfortable for long periods of time so you don't develop fucked wrists and whatnot...

    And, yeah, it is a pain in the ass getting everything going on Linux that Afterburner does in one program. Really not worth going down that rabbit hole.

    Fun fact most servers use stuff lighter than xfce.

    Lxde and lxqt are in fact lighter than xfce. Lot of server target configurations in fact end up using Openbox that is in fact lighter again.

    Debian testing/sid is good for a lot of things. Sorry xfce is not the best all round desktop particularly once low memory comes a factor. Yes xfce was the go to low memory desktop but these days the lx developers with lxde and lxqt hold that crown.

    So just another not factual comment.
