[nsp] High CPU question (update)

[David Flynn]

Right, off the top of my head 40Mbit/sec at 128byte frames is nearly
40kpps, and at 64byte frames it will be 80kpps.

>From a quck glimpse at your config you have netflow turned on.  Netflow
attempts to speed things up by caching details obtained from the first
packet so that they don't need to be calculated again later.  If the
packets do not form long lived flows, eg worst case, every packet is
unique of destip/srcip/destport/srcport, then each packet has to have
the full hog of netflow stuff done to it.  This *will* kill the 7200
platform at the sorts of pps values you are talking about.

Try turning it off, see if that helps.
