minus-squareMangoPenguin@lemmy.blahaj.zonelinkfedilinkEnglisharrow-up3·4 months agoThat sounds neat! I’ve always read the performance hit of a VM is pretty minimal, like 1% or less on most tasks. Is it really that much faster for you?
minus-squareF04118F@feddit.nllinkfedilinkarrow-up1·4 months agoI’m not actually sure because I haven’t measured it. But I’ve read that while CPU and memory overhead is small, disk IO is much faster without virtualization.
minus-squareMangoPenguin@lemmy.blahaj.zonelinkfedilinkEnglisharrow-up1·4 months agoIt could be depending on the underlying filesystem and how it’s set up, I’ve run into that before. But my self hosted stuff doesn’t need particularly fast disk IO, so I don’t really notice even if there is a bottleneck lol
minus-squareMangoPenguin@lemmy.blahaj.zonelinkfedilinkEnglisharrow-up1·4 months agoYeah I’m running ZFS with raw disks, and most things are in containers anyways, just a few VMs for Windows or stuff that doesn’t like containers.
