Hello Alexandr. Close reverse your thinking. Fast path is ASIC slow path is CPU. The only data that should be going slow path are packets to the switch, telnet, snmp, route protocols etc. If in band traffic is going through the CPU it usually is linked to a mistake configuration redirects as an example or the tables on the switch are full and thus the switch treats it as an unknown packet.

Hope that helps
