Even 100KB seems a couple of magnitudes slow for the emulated E1000 between 2 guests on the same host. > > Do you have an idea why this is so slow? > Try disabling checksum offloading (and TSO/LRO if Virtualbox supports that). > And why the if_vtnet network driver isn't provided in GENERIC kernel? > Is it still under development? > Getting it in GENERIC is in my plans. My spare time has been distracted at some other Ethernet drivers for the last few weeks. I hope to spend much of my spare time in Dec. on various VirtIO items.
