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 if I'm closer to device limits, or kernel limits? I want to say that I'm don't know if 8000 irq per second means a high IRQ use or a lower user. I hope I've explained better at this time. -- Thanks, Jordi Espasa Clofent
