You can use show controller cpu to help see whats going to the cpu Make sure you have no ip redirects and no proxy arp on all the interfaces. How many routed interfaces do you have ? The output below for "max" is for 8 routed interfaces if you have more you should change to the desktop switching template. With your roughly your values for indirectly connected routes and 13 ip interfaces on a box I needed to switch the template "sdm prefer routing" requies reload.
