[Xen-users] Bandwidth between VMs on Xen

[Jaya Dhanesh <jaya.dhanesh@xxxxxxxxxxxx>]

Hi,

I created 2 vm and connected them using a bridge. The bridge was created using brctl command.
I set the mtu of the interface in the vm and the bridge to 4096. When I tried to copy an image from one vm to another it was very slow and the rate was 30 kbps. But when the mtu was reduced to 1500, the rate increased to 3 mbps.  How does an decrease in the mtu increases the transfer speed?

Thanks,
Dhanesh.
