Re: New tramp observations

You should have seen the performance improvement :-) The dark side are stale caches. You can control Tramp's caching behaviour by the variable `remote-file-name-inhibit-cache'. This is a GNU Emacs variable, which is acknowledged by Tramp. Maybe it shall also be introduced in XEmacs 21.5. Its definition is --8<---------------cut here---------------start------------->8--- remote-file-name-inhibit-cache is a variable defined in `files.el'. Its value is 10 Documentation: Whether to use the remote file-name cache for read access. When `nil', never expire cached values (caution) When `t', never use the cache (safe, but may be slow) A number means use cached values for that amount of seconds since caching. The attributes of remote files are cached for better performance. If they are changed outside of Emacs's control, the cached values become invalid, and must be reread. If you are sure that nothing other than Emacs changes the files, you can set this variable to `nil'. If a remote file is checked regularly, it might be a good idea to let-bind this variable to a value less than the interval between consecutive checks. For example: (defun display-time-file-nonempty-p (file) (let ((remote-file-name-inhibit-cache (- display-time-interval 5))) (and (file-exists-p file) (< 0 (nth 7 (file-attributes (file-chase-links file))))))) --8<---------------cut here---------------end--------------->8--- In your case, either set this variable to `t', or to an appropriate number you feel able to deal with. GNU Emacs' default of 10 might be a good compromise.
