+** TRAMP
+TRAMP is a package which provides remote editing capacities. It is particularly useful for remote server management.
+
+One of the reasons why TRAMP may be slow is that some plugins do too much requests to filesystem. To debug these issues, set the following variable to 6:
+#+begin_src emacs-lisp
+(setq tramp-verbose 1)
+#+end_src
+
+To check if a file is remote, you can use ~file-remote-p~. E.g. ~(file-remote-p default-directory)~ for a current buffer. The problem with this approach is that it's rather awkward to add these checks in every hook, especially for global modes, so for now I just set environment variable for Emacs which disables these modes.
+
+So far I found the following problematic plugins:
+| Plugin              | Note                                     | Solution                      |
+|---------------------+------------------------------------------+-------------------------------|
+| editorconfig        | looks for .editorconfig in the file tree | do not enable globally        |
+| all-the-icons-dired | runs test on every file in the directory | disable                       |
+| projectile          | looks for .git, .svn, etc                | advice ~projectile-file-name~ |
+| lsp                 | does a whole lot of stuff                | disable                       |
+| git-gutter          | runs git                                 | disable                       |
+| vterm               | no proper TRAMP integration              | use eshell                    |
+
+At any rate, it's usable, although not perfect.
