Hello, I have a question about the performance changes to PF introduced in 10.0. I understand that PF is now able to take advantage of multiple CPUs / SMP better because of finer grain locking. Does this also apply to using ALTQ w/ HFSC? Can I expect packet forwarding performance to increase when upgrading from 9.x to 10.x when using ALTQ? My understanding is that ALTQ is still locked to a single core, or is this no longer true? Also, I compile my igb driver with the LEGACY_IGB_TX to be able to use igb(4) interfaces with ALTQ. Can I still expect to see a performance increase with the PF changes in 10.x? Thanks, -Nick
