2428800 bytes (52 MB) copied, 56.0124 s, 936 kB/s wow that' sslow :) jdoe: what's that from? dd? well, nevermind, it's obvious it's from dd but to a VPS disk? yeah, I guess someone was swapping again. 1073741824 bytes transferred in 160.664508 secs (6683130 bytes/sec) (on the new-KVM VPS) 1073741824 bytes transferred in 25.782896 secs (41645509 bytes/sec) on the old-KVM VPS I wonder if they're both using virtio i get slower speeds on the new kvm than old kvm myself not using virtio there may be more people actively banging on it. or it may be a differently specced machine. i think it's just non-virtio sucks with the new kvm well at least with openbsd it was stalling something chronic 104857600 bytes transferred in 13.731 secs (7636124 bytes/sec) hmm that's faster than last time ya, looks like new-VPS is using PIIX3 I may have up_the_irons change that to virtio thing is, dd doesn't show nearly as bad as extracting a tarball i want to try virtio, but it seems it needs to be set to virtio xen works automagically with virtio drivers ya, in the VM config ie you don't need to change the config dd is a streaming write, tar is (somewhat) random. I can't imagine tar being much more random than a /dev/zero stream i found when extracting a tarball it'd just stop for long periods of time and if you used tmux and tried to open a new shell it'd take like 30seconds+ though it is a read/write cycle instead of just pure write pciide0 at pci0 dev 1 function 1 "Intel 82371SB IDE" rev 0x00: DMA, channel 0 wired to compatibility, channel 1 wired to compatibility is that PIIX3? wd0: 16-sector PIO, LBA48, 20480MB, 41943040 sectors what! it's not even dma no wonder it's slow wd0(pciide0:0:0): using PIO mode 0, DMA mode 2 hmm.. maybe it is i dunno i was reading web sites today, and apparently you can get 1tb raptor hard-disks now, 10k rpm but they're so expensive :( Lefty: we use libvirt plett: Lefty : yeah, we also use XML generated from our own stuff, not virt-install jdoe: which host was that, that was slow? mercutio: is that stuff you're looking at on the beta vps?
