With 1800 interfaces in the system Freebsd seems to use about 50Mhz of cpu when idle in "interrupts" even when there are no interrupts to process. on a 500Mhz box it uses 10% of the cpu and it seems linear with different speed processors. the 1800 interfaces are 900 DLCIs on a T3 frame with 900 bridge groups (rather common for a DSL delivered via Frame). This with just one line...the same problem could occur with say 8 T1 lines with 100+ DLCIs on each. It seems that there is substantial overhead just scanning interfaces for some routine maintenance...is there any hope of alleviating this deboggle?
