Dear colleagues.
I have troubles with L3 switching on my C8510MSR box. CEF is running,
CEF and ARP tables builds correct, but packet switches via RSP process switching (IP input) with high performance degradation. There is no special configuration, it terminates 5 dot1Q trunks only. Any suggestion would be greatly appreciated. I have:

There is certain traffic that need to be process switched. What is configured on this FE
