Ssh lagging

Hello forum,
I’ve installed HA in a plain state, everything is shared globally over the OS (Armbian for this case), but the HA user has no privileges and no login.

Typing is not showing as long as 10 seconds.
The report of TOP showing just a CPU load less 3%, but I suspect a huge network traffic, which might cause low response to the ssh session.

How to track the cause that HA makes so much slowdown during a SSH session over the wireless?

BTW, HA installed on Asus TB S.

Try using the netstat command to look at network traffic.

I can’t figure it out.
My solution will go for stopping HA, during ssh session. That is mostly a maintenance situation, so HA might be off for the accessing time.
