I had 7206-NPE-G1 for routing purposes and PBR, IP CEF is on, no ACL, no dynamic routing just static.
Well 1 gbps in and 1 gbps out. That is all. CPU was about 82% as highest.
After that decided to replace 7206-NPE-G1 with 7201 (G2) as it should be TWICE as stronger.
But nothing of the kind!!!
We have the same 82% as highest, not 41% as was expected.
I promised to my boss to lower CPU load at least 1,5 times...
