OT: High interrupt cpu usage on 7206...

is driving me nuts :(

I'm trying to nail down what is taking a 7206 with G1 to its knees
with just about 50Mbps (75%/72% cpu).

The config has many things, like WCCP, QoS, PBR, NBAR and OSPF + BGP,
but still, 50Mbps for a G1 should be a breeze, shouldn't it ?

I'm seeing some SPD flushes, trying to make sense of them.
But I would not mind advice on what to look after.
(I was hoping CSCtg42179 would save my day, but upgraded to 12.4.24T8
and same thing...)

TIA,
