I'm afraid I can't use iostat on a VPS. Shows me a Cannot find disk data
warning and dies. Googled it a bit and found a bunch of iostat doesn't
work from inside containers and it would be a security issue if you could
have that kkind of access to physical drivers from inside a virtual
machine.
Did a ioping instead. I believe it does the trick of measuring.
Here's what I got:
*4.0 kb from . (ext4 /dev/ploop48624p1): request=1 time=283 us4.0 kb from

Wow that's some pretty ridiculous I/O lag. It's pretty obvious the VPS you
have isn't intended for anything I/O intensive (or has too much I/O
intensive stuff on it already). I'd recommend moving to a VPS provider
that has fully virtualized containers rather than the para-virtualized ones

SSD might help, but only might.
If you think about the underlying machines they are limited on the
dimensions of CPU, RAM, and disk. If the provider uses SSD that would
generally improve the disk performance but if that means they then cram
more customers onto the box because they have
Any idea of how many IOPS would be needed for hosting a decent srcds with
replays enabled!? I've had one host offering me 100 but I'm not really sure
how is that converted to latency. I know it isn't a direct relation, but I
think it might depend on the hardware specs.
Anyways, I just wonder if
Hmm, I'd say try disabling re-plays for a while and see if that makes any
different. That might generated a lot of (unnecessary) traffic and
storage I/O on an ad-hoc basis. If that makes things better, than that
might indicate you need storage I/O (i.e. find a host that uses all
solid-state
You can't tell from that number alone. Same as on the CPU dimension your
provider can sell 100 IOPs to 30 customers on a disk subsystem that
might provide, for examples sake, 800 IOPs. Theoretically it limits the
damage one customer could do but overall the system is still oversold -

Yeap. Got replays disabled for a while as long as logging. Though it is a
feature our community misses and we can't afford to have it disabled for
the long run. But yeah, the stuttering gets considerably better with
replays and logging off. I don't think I got what you said about storage,

What if they guarantee *my VPS* will have the 100 IOPS?
You've reached the limits of my knowledge :]
BTW I neglected the read ops before. I don't have useful data for a
single TF2 instance (I typically run ~4 TF2 servers per VPS) but one of
