Hi Dmitry and Michael:
I enabled the project-mode-line recently and now when I try to open a
remote file emacs seems frozen forever (minutes in a not so bad
connection).
I made a profile and it looks like there is some bad interaction between
project-mode-line and tramp names
I already tried:
(connection-local-set-profile-variables 'my-profile '((project-mode-line . nil)))
(connection-local-set-profiles '(:application tramp :user "myuser") 'my-profile)
But is not disabling the modeline for remote files.
And
vc-ignore-dir-regexp (format "\\(%s\\)\\|\\(%s\\)" ;; disable vc on remotes
vc-ignore-dir-regexp
tramp-file-name-regexp)
But the project-try-vc is still trying in the remote files.
The profile report:

At the moment I disabled the project-mode-line. However There may be
a better solutions for this issue.
