multiple routing tables roadmap

2007-12-26 Thread Julian Elischer
On thing where FreeBSD has been falling behind, and which by chance I have some time to work on is "policy based routing", which allows different packet streams to be routed by more than just the destination address. Constraints: I want to make some form of this available in the 6.x

Dear Jordi, In theory, on a Gigabit link you get 1 000 000 000 bits * second. By default you have the MTU set to 1500 bytes which makes ~12 000 bits. 1 000 000 000 / 12 000 = ~ 83 333 packets per second. 83 333 packets per second makes 0.08 packets per microsecond. 1 / 0.08333 = 12.0 microseco

OK, I'll try to explain in another way. While I've done network performance test I've monitored the IRQ rate, and, for example, it's a 7000/8000 interrupts per second in every NIC (I use 2 NICs in a bridge). The question is ¿how can I know if this irq rate is too high or not? ¿how can I know
