Personally, I'd appreciate that. TCP's congestion control when using
100MBit Ethernet seems to work fine (as there are no complaints?) so I
see no reason why the bandwidth shouldn't be unlimited in general and
TCP should adapt to the available bandwidth. If one wants to limit
bandwidth manually, that's possible of course.
I don't know if such a change would affect all other existing ways of
saving a VM, with different consequences?
regards,
thomas
