Tramp slows down some edits of a remove file |

Greetings!
I am using Emacs+Tramp on a regular day basis and experiencing some
performance issues.
When I make the first edit (insert any char or even hit backspace) on a
remote file I just opened it lags. Any edit after that seems to be fine.
Any edit after another save is slow again.
This does get worse on slow connections but this lag is quite disturbing
even on fasty connections.
To give an idea I've recorded a screencast
https://www.mikpom.ru/owncloud/index.php/s/PQMtZuoffSr8tP8
Any help is appreciated and I am willing to help debug and investigate
if needed.
Kind regards,
-Mikhail

Thanks for the feedback, I'm closing this bug. I've added also the
