I have written an application which contains two kernel threads that takes mbufs directly from a network interface and forwards to another network interface. This idea is to simulate different network environment. I have been using FreeBSD 6.4 amd64 and tested with an Ixia box (specialised hardware firing very high packet rate). The PC was a Core2 2.6 GHz with dual ports Intel PCIE Gigabit network card. It can manage up to 1.2 million pps. I have a higher spec PC with FreeBSD 7.1 amd64 and Quadcore 2.3 GHz and PCIE Gigabit network card. The performance can only achieve up to 600k pps. I notice the 'taskq em0' and 'taskq em1' is solid 100% CPU but it is not in FreeBSD 6.4. Any advice? Many thanks in advance Joe
