In freebsd 6.x, the interrupt is very high if the traffic increase.. However, Freebsd 7.0, the interrupt issue is improve a lot (at least 10x improve). But the new issue come out whereby the Zebra daemon is CPU utilization is very high as running on 40% if the traffic for that router go up to 80Mbps. This is not happen to 6.x routers but only 7.0 routers which currently I've 3 units and all of them have the same issue. top: 1273 root 1 69 0 70120K 66632K select 1 26.8H 32.76% zebra >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
