Thanks
That explains a lot ....
I guess until we can afford / source / upgrade to 10Gig capable
infrastructure, we're stuck with bonding and the issues that you
describe.
It's certainly going to be better than the packet loss we'd see
trying to squeeze 1.6Gbit of traffic down a 1Gbit connection I guess
- even if we have to bond 3 GigE links together to ensure we allow
for over head
