For some reason, our VMs are only allowing speeds of 1.0-2.0mbps downloads ... even though each are on full gigabit ports ...
 
Node to VM - I get about 30 mbps

Node to Node - I get about 200mbps

Node to external server - I get about 50 mbps

VM to external server - I get 1 mbps ...

Hi,
much to less!
What kind of nic do you use for the VMs? Which OS is running inside the VMs?

On my servers iperf shows values between VMs on one node from 3.15 GBit/s up to 6.3 GBit/s (depend on the server).
But all are linux-VMs with virtio.
