Why both the bandwidth and latency performance are dropping so dramatically with multiple VQ?What's the expected benefit from multiple VQsHeh, the original patchset didn't mention this :) It really should. They are supposed to speed up networking for high smp guests.If we have one queue per guest CPU, does this allow us to run lockless? Thanks, Rusty.
