It is highly appreciated to work on this. However, don't expect that it
will help much in Tramp optimization.
In my experience, most time in Tramp is spent on wire. That is, sending
commands to the remote shell, and reading the command's output. Compared
with this, time spent in Elisp is not so important (although any
optimization will be appreciated as well).
In Tramp it is hard to compare the spent time. Mainly, due to different
network latency in different environments. And this can change even in
your local LAN over the day, so that you cannot be sure whether an
applied optimization helps, or not. I know what I'm speaking about,
because I'm working in this area the last weeks.
What I use for Tramp optimization is to count the number of commands
send to the remote host. The less commands are sent, the better.
As a poor man's approach I trace the Tramp functions tramp-send-command
(all commands sent to the remote shell go through this) and
tramp-file-name-handler (all invocations of Tramp functionality pass
this function). The latter is to know, what Emacs primitive function has
caused a remote command.
So I test something like this
(let ((remote-file-name-inhibit-cache t)) ;; Do not use file caches.
(trace-function-background 'tramp-send-command)
(trace-function-background 'tramp-file-name-handler)
(ignore-errors (kill-buffer trace-buffer))
;; The test.
(with-temp-buffer
(insert-file-contents "/ssh::.emacs" nil 100 nil)))
The *trace-output* for this example is appended.
See also the discussion in bug#56342.
Best regards, Michael.
