Hello Project summary ================= ptnet is a new multi-queue paravirtualized device that builds on ptnetmap to allow VMs to exchange TCP traffic at 20 Gbps, while still offering the same ptnetmap performance (10-100 Mpps) to native netmap applications. The purpose of this SOC project is to write a ptnet driver for FreeBSD and a corresponding device model for the bhyve hypervisor. Status update for week 9 =================== In week 9 I did some code cleanup, sharing more code with the linux driver. I tested the performance of the FreeBSD ptnet driver over QEMU-kvm, which give ~20Gbps TCP_STREAM and 40Ktts TCP_RR tests, which is aligned to the performance of the linux driver over the same hypervisor. I also started to take a look at bhyve and libvmm, to familiarize with the code, build system, and fix/extend the netmap support. This week (10) I will keep working on bhyve, trying to come up with a first skeleton of the ptnet model implementation.
