Even VMWare understood that and implemented it as big new feature in their vmxnet3 drivers. Don't get me wrong, some of the vbox network stuff is pretty nice (like the 802.1q vlan implementation in bridging (which explodes only in 3.10.7 kernels on guest when using around >100 vlans)), but in the end it does not save you because the latency is simply not good enough for todays' networking experience with LAN latencies of less than 0,1 ms. -- Regards, Stephan ------------------------------------------------------------------------------ Introducing Performance Central, a new site from SourceForge and AppDynamics.
