Slow download speeds openvz

[asmar]

Hi all,

I've got a new node with only two vm with no traffic at all since I don't use them yet to serve any service.
I can download with up to 60-80Mbit/sec fine inside the vm but when I'm trying to download outside the vm I'm getting very slow speeds, max 3-5Mbit/sec.

Any ideas how I can troubleshoot this?

Many thanks

Hi,
I've exactly the same problem !
Do you have find any solution ?

For my own, VM speed with iperf is like this :

root@myserver:~# iperf -c iperf.ovh.net -i 2 -t 10 -r

I'm losing my mind...
