Poor performance with tramp

[mavit]

I found all-the-icons-dired to be unusably slow on a remote tramp directory containing a few hundred files. Commenting out the following line improved performance a great deal:

	(if (file-directory-p filename)

I faced a similar issue as part of spaceline-all-the-icons here

You can use the following to decide whether or not a file is tramped and optimise around that maybe?

(file-remote-p filename)

Unfortunately, that doesn't really help solve the problem as I guess you'll still want to know whether or not the file is a directory and it's still costly to run any of the file commands on tramp files! 😅

I'm not sure whether f.el performs any better... But ideally, you'd want to interface with tramp

I think file-remote-p might be helpful, but if not, try file-local-name. It works well for me.

I am seeing this slowdown also.

Is there a annotate-folder-names-with-icons hook where we can count the number of items in the dired buffer? We could then make a decision on whether to render based on that.

I was getting slow performance and fixed by running loop unless it is a remote directory. I faced the same issue with Centaur Emacs too. There the suggestion was to advise projectile, but that didnt help much. But this fix makes it much faster.

(defun all-the-icons-dired--refresh ()
  "Display the icons of files in a dired buffer."
  (all-the-icons-dired--remove-all-overlays)
  (unless (file-remote-p default-directory)
