INIZ : NL2KVM Node IO?
Is it just me or any one on that node is experiencing similar low IO speeds?
CPU model : QEMU Virtual CPU version (cpu64-rhel6)
Number of cores : 3
CPU frequency : 3492.064 MHz
Total amount of ram : 1006 MB
Total amount of swap : 511 MB
System uptime : 21 days, 1:35,
I/O speed : 6.5 MB/s
I have to VMs running on Identical setup(Ramnode & INIZ), running nothing crucial but VM at INIZ goes crazy after sometime of use. I did change the drivers as suggested by patrick (virtio), performed well for that particular day but it's back to these low speeds.
PS: I don't spam this command, I only run it if I feel there's a lag.

Why not submit @iniz a ticket?
Because that's too much effort, plus he is kind of asking a question.
I can't speak for KVM with iniz only OVZ. But never had such issues.

Abuser on the node?
Typical excuse?
It doesn't have be an excuse, There could be someone writing huge files on their disks, and that could explain why his I/O speed is low.
It was a joke.. http://lowendtalk.com/discussion/comment/548091
It's fine and and have no sympathy for people who open threads just to moan.
The 99% of other users on the node are happy with no issues.
Assuming guide on our KB was followed results are normal. I've seen it drop to around 200 mark but that is satisfactory for most.

Redacted.
Moan? Now questions with Hosting Provider's name on it is considered moaning? Sympathy? wow that attitude.
Yes, your KB was followed the day the VPS was installed.
Hard to believe but a post here did improve the IO. No wonder why it's not going below 150<.
