MD5 BGP performance on a VXR?

Has anyone done any concrete testing on how well a 7206VXR with an
NPE-300 can handle BGP MD5? The box in question has about 25 sessions
and is pushing 150Mbps, with a 75% cpu load. I'm curious to know if it's
the MD5 taking all the CPU.

Thanks,
Ben

sh proc cpu should be able to tell you where the load is..

i have a 7206, about 130 bgp sessions (445000 paths) .. not much cpu being used,
BGP scanner is the larges with a 5% 1min average
