How fast can you I/O on your LowEndBox?

Legendlink

For me it's less that I actually need that high of an I/O and more of I like to see that the providers take pride in their service to give you the best overall performance. Also, that they don't overload their nodes to the point where things seem so sluggish.

/tmp is a tmpfs so that doesn't really count

try from /root

Oh i always thought /tmp was just located on the normal file system.

Anyway here you go with /root/, not much of a difference though

Are you not mistaking that with /dev/shm ?

+1

But, not always. For example my vserver at edis allocates 16MB for /tmp in RAM

Francisco

@miTgiB said: Are you not mistaking that with /dev/shm ?

That too, but i'm seeing it a lot more instances where /tmp is a tmpfs as well (debian, etc).

You're assuming that the OVZ devs actually coded something correctly

I'd say for the price, under 3 pounds a month, this is a keeper!

I'm thinking iops and stable latency to storage medium is more important than write speed, so how about we change this test to "ioping . -c 10", would be interesting to see what kind of iops people get with their vpses .

I bet this one works so much better than any BuyVM hitting 500MB/s+ sequential write but only gives couple hundred iops.

Exactly. And at the end of the day it's all irrelevant. 'dd' and 'ioping' scores correlate more closely with phases of the moon than with real-world performance.
