[c-nsp] 3845 maxing out at 400 Mbps

[Frank Bulk]

Just an update -- I shuffled interfaces last night, so that the bulk of the
traffic goes through the 3845's native GigE interfaces.  This has reduced
CPU by about 10 to 15% and my new max is 423 Mbps, already 5% my previous
max.

Thanks for the help.

Frank

I guess so. This issue was discussed some time ago on frnog mailing
list (french nanog)

After asking earlier today, I told myself that you would already use
the hwic for the inter-3845, but it appears not.

Things should improve if less traffic flows through the hwic.
