Description

With pfSense version 2.4.4 and the usage of ntopng package the CPU is constantly on a high load.
Reducing ntopng tasks does not help, nor restriction to LAN interface and network only:

Startup line: ntopng --data-dir "/var/db/ntopng" --pid "/var/run/ntopng.pid" --dont-change-user --daemon --http-port "0" --https-port "3000" --interface "igb0" --dns-mode "0" --local-networks "10.21.30.0/24"

Even with no network traffic at all the CPU usage is around 5-10% in IDLE with an AMD GX-424CC Quad Core CPU and 8 GB Ram on bare metal and changing from second to second while keeping high load. Intel i350-T4 V2 card, 1 LAN, 1 WAN with latest ntopng Package running: 0.8.13_1 = 3.4.180911

Other CPU intense services like snort consume less than 0.3% in IDLE.

According to other users they have the same issue:
