    Default BFQ Scheduler Still Trying For The Mainline Linux Kernel

    Phoronix: BFQ Scheduler Still Trying For The Mainline Linux Kernel

    With the latest patches sent out today, the BFQ I/O scheduler is still trying to get accepted for the mainline Linux kernel...

    Cool Bravo!

    It seems it comes from Italy: it'd be the "Renzi effect"!

    I wish this gets accepted. I'm really tired of the disk locking up the entire system every time...

    This will not help with that at all. BFQ is snake oil.

    Bullshit. Been using it for years, alongside other machines with CFQ.

    Just for clarity: Are you saying that this scheduler prevents the huge slowdowns when swap is used?

    Interestingly, one user wrote:

    Swap serves another (often underrated) purpose: Graceful degradation.

    If you have a reasonably amount of swap space mounted, you will know you are running out of RAM because your system will become noticeably
    slower. If you have no swap whatsoever [or if it is filled too quickly], your first warning will quite possibly be an application OOM killed or losing data due to a failed memory allocation.

    Think of the slowness of swap as a _feature_.
    And another one wrote:
    Swap is useful as a safety belt. When you get an application that starts eating up all your system memory, you'll notice that your machine suddenly became slow, and, hopefully, will be able to kill that app before your swap gets exhausted.
    The BFQ scheduler should prevents the huge slowdowns when doing operations that use a lot a hard disk but while the user tries to use the GUI meanwhile, etc.

    Heh, it's a feature.

    I'll tell that to the crowd next time we are watching a movie and I forgot to disable emerge linking libreoffice in the background using lto.

    If I tell em that the sudden inconvenient break is caused by a feature they will *surely* understand lol.

    I'm sorry, I refuse to take that seriously. Thank you for your post though. You have given me a good laugh, thank you sir.

    Is there an XKCD for this yet?
