Hi,
From -Q:
1. C-x C-f
2. Experience delay
3. C-g
4. C-x C-c
Depending on where Emacs is started, loading tramp is triggered and
there is a delay before the prompt is shown. The delay is about a
quarter second on my system. This is quite noticeable.
Stracing emacs started in two different directories and executing the
recipe, one log is 6884 lines, the other 1949. The extra 5000 lines
looks like emacs is opening every library known to it, finishing up by
reading ssh/netrc/rlogin files.
In GNU Emacs 26.0.50.1 (x86_64-unknown-linux-gnu, X toolkit, Xaw scroll bars)
of 2017-02-17 built on logos

Not reproducible on MS-Windows, but maybe the place "where Emacs is
started" needs to be defined in more detail. Can you tell in what
directories it happens for you?

My home directory is the only one I'm aware of.

I see this also on GNU/Linux (with master, not emacs-25), here's a
backtrace from doing (debug-on-entry 'require) before the C-x C-f:
Debugger entered--entering a function:
* require(tramp-compat)
byte-code(...)
load("tramp" noerror nomessage)
(and (null load-in-progress) (load "tramp" (quote noerror) (quote nomessage)))

(if (let ((default-directory temporary-file-directory)) (and (null load-in-progress) (load "tramp" (quote noerror) (quote nomessage)))) (apply operation args) (tramp-completion-run-real-handler operation args))

I've pushed a fix to master, which shall avoid loading tramp.el just for
file name "/". Since it changes autoloads, it might be necessary to
bootstrap Emacs.
Best regards, Michael.
