Rusty Russell fb6813f480 virtio: Recycle unused recv buffer pages for large skbs in net driver ... If we hack the virtio_net driver to always allocate full-sized (64k+) skbuffs, the driver slows down (lguest numbers): Time to receive 1GB (small buffers): 10.85 seconds Time to receive 1GB (64k+ buffers): 24.75 seconds Of course, large buffers use up more space in the ring, so we increase that from 128 to 2048: Time to receive 1GB (64k+ buffers, 2k ring): 16.61 seconds If we recycle pages rather than using alloc_page/free_page: Time to receive 1GB (64k+ buffers, 2k ring, recycle pages): 10.81 seconds This demonstrates that with efficient allocation, we don't need to have a separate "small buffer" queue.
