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.

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

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?
