  • Awesome, so that’s good news. Disks probably just fine.

    My next thoughts are on the service itself then… Your service providing the share might be getting throttled or not getting direct access to kernel hooks for performance.

    Simplest test I would think is set up Samba or NFS in the host itself, not a container. Try a large transfer there. If speed isn’t an issue that way, then something at the container level is hindering you.


  • Hmm, at a glance those all look to be CMR.

    To rule this out ideally, a tool like iostat (part of sysstat tools) can help. While moving data, and with the problem happening, if you run something like “iostat 1 -mx” and watch for a bit, you might be able to find an outlier or see evidence of if the drives are overloaded or of data is queueing up etc.

    Notably watch the %util on the right side.

    https://www.golinuxcloud.com/iostat-command-in-linux/ can help here a bit.

    The %util is how busy the communication to the drive is… if maxed out, but the written per second is junk, then you may have a single bad disk. If many are doing it, you may have a design issue.

    If %util doesn’t stay pegged, and you just see small bursts, then you know the disks are NOT the issue and can then focus on more complex diagnosis with networking etc.









  • Drive failures have almost nothing to do with access if they are mechanical. Most failures are from bearing or solder interconnect failures over time.

    Also, most seeding is in smaller chunks that are read and cached if popular… Meaning less drive hits than 1-1 read vs upload.

    You will almost always have drives fail from other aspects like heat or power or old age before wear from seeding would ever be enough to matter.

    I have drives in the excess of 10+ years, with several seeds that have been active for many years of those, that are still running just fine.








  • 95 can suck eggs… The GUI was largely items they had co-developed with IBM for the next release of OS/2 that they instead split last minute due to contractual arguments since Microsoft wanted a larger cut of profits. There’s more depth of course but tldr version.

    It’s a large part of why 95 was so crashy until osr2.5… it was largely 32 bit GUI stuck onto rushed 16 bit DOS with some quick protected mode hooks.

    That said, XP was the first version I could stand.

    7 was actually pretty good.
