High "Unclassified" CPU load

Hello there. Bought “HAP lite ac” recently. At first struggled with configuration for PPPoE+VPN, it’s working now tho. But i have 90-100% cpu load with 20mbit-ish torrent activity (150 connections total), and profiler tells me that 20-25% of it is unclassified. No difference with ROS upgrade from 6.39 to 6.42rc. Please have a look.
