I have a VM host with a Gigabit network connection hosting about 5 guest OS's on a bridged virtual network.
The problem is that the VM Host (including all guest VM's) is only able to transfer at about 100K/s on the network despite there being ABSOLUTELY NO network traffic whatsoever. The odd thing is that this only happens in upstream transfers. Downstream transfers are still normal.
Any ideas as to the cause?
I have narrowed the culprit to being the 100Mb HALF DUPLEX network connection on the VM host. This is causing an effect of network transfers only being fast in one direction.
