weel that is fine - but it really doesn't provide the complete
picture.

First of all 15% arp seems VERY high, do you by change have any static
route with only a Ethernet interface as next-hop ?

Secondly, enabling CEF might help you, if your traffic can be CEF
switched with the features you're running.

conf t
ip cef
end
