I have installed
daemons on top of the Linux mail 4.14.98+ #1200 Tue Feb 12 20:11:02 GMT 2019 armv6l GNU/Linux
Also, I have connected rpi0 to another rpi over usb-otg (to have a serial and ethernet access).
Unfortunately, even though rpi0 has low load, when ssh to it, every typing takes seconds, and in lot cases connection break due to timeout.

When I connect to rpi0 via serial link - everything works fine, no delays, no timeouts.
So, question is -- which software may cause a delay?
