Can you elaborate on what exactly is imposing this bandwidth limit?  You
need to provide a lot more detail about your setup so we can understand
what the actual problem is.  Start with the hardware involved, whether a
single machine or a group of machines, what virtual platform you use
(KVM/Xen/etc), and what application you are dealing with (http, smtp,
imap, other?).  Are you attempting to increase inbound or outbound
bandwidth, or both?
