I installed the NIC to the shared PCI slot and it has helped, but not as much as I expected. Now that all NICs are sharing an IRQ, interrupt usage has dropped from ~90% to ~70%. I'm pushing about 25 kb/s across two NICs, which makes me wonder the max throughput I can expect on a firewall on

Hey Bob, Thanks for the info. I originally asked as I'm seeing between 80 and 90 percent interrupts on a gigabit firewall with some em(4) cards. I think my issue may be expected given the scenario, so I'll pose that question to the group in a different thread. thanks, sk Bob Beck wrote:

the idle loop problem will affect any driver that uses tsleep where stuff might need to be serviced from the idle loop. the bge booboo I found and fixed earlier with krw was that of it not testing correctly if interrupts were for itself in the shared interrupt case. totally differe
