Or make some network dumps (see tcpdump and wireshark) and compare the netw= ork traffic. Maybe one of them handles smaller packets or something like th= at. You can also look at this: # netstat Active Internet connections Proto Recv-Q Send-Q Local Address Foreign Address (state) = =20 tcp4 0 0 rpi4.thuis.DDDD..ssh MacBonkers.thuis.55545 ESTABLISH= ED tcp4 0 0 rpi4.thuis.DDDD..jetdi monitoring.thuis.17925 ESTABLISH= ED udp6 0 0 2001-XXXX-YYYY-7.ntp *.* =20 udp4 0 0 localhost.ntp *.* =20 If Recv-Q contains a lot of bytes it means the application is not fast enou= gh in handling the incoming traffic and the OS will throttle the traffic at= some threshold.
