Subject: 26.0.50; Saving files on remotes very slow if shell buffer is open
Date: Fri, 22 Dec 2017 21:38:34 +0100

Hi,

I am observing a rather weird interaction between tramp and comint. Saving and
editing files on remotes is pretty snappy till I open a shell buffer. Once a
shell is open it can take good 10s to save a buffer. Editing and navigation are
also impaired.

Steps to reproduce:

  1) emacs -Q
  2) /ssh:remote-host:tmp.txt
  3) save tmp.txt (snappy)
  4) M-x shell
  5) back to tmp.txt and save (terribly slow)

Can anyone reproduce this?

  Vitalie
