I replaced a 3550 non G with 3560 non G. The config was the same (copy & 
paste).
On 3550 average CPU load was below 1%. On 3560 the load was always above 
5% with spikes up to 60%.
After some googling I change the sdm template. The load went down, but 
above 5%. I put extensive ACL's on all the routed port and finally CPU 
stabilized to around 5%. The load is caused by "IP Input" and "HL3U bkgrd".
My feeling is that C decided to discourage the use of c3560 for routing 
and somehow they reduce the switch fabric.
