browse-url-emacs has always been inexplicably slow for me,
since at least Emacs 24 (but maybe just 'always').

I've just done some basic benchmarking with:

(benchmark-run (save-selected-window
                  (browse-url-emacs "http://www.example.com")))

;; If I delete the "www.example.com" buffer after each attempt, this
;; call takes nearly 3 seconds:

(2.819470404 1 0.046148434000000016)
(2.669529036 0 0.0)
(2.837350438 1 0.02421054800000011)

;; If I retain the "www.example.com" buffer, then each retry takes
;; <0.5 seconds:

(0.374270464 0 0.0)
(0.428719681 0 0.0)
(0.476068586 1 0.044311528999999794)

;; Whereas benchmarking only `url-retrieve-synchronously':

(benchmark-run (url-retrieve-synchronously "http://www.example.com"))

;; This takes <0.25 seconds.
(0.172364234 0 0.0)
(0.24314511600000002 0 0.0)
(0.19534228 0 0.0)

;; Deleting the network connection via M-x list-processes between
;; attempts adds about 0.25 seconds for all sets of benchmarks, so the
;; network connection time is not a factor.

;; eww is also fast:

(benchmark-run (save-window-excursion (let ((eww-retrieve-command 
'sync))
					(eww "http://www.example.com"))))
(0.197008672 0 0.0)
(0.25098304499999996 0 0.0)
(0.28419454299999997 0 0.0)


So something to do with browse-url-emacs is taking an additional 2.5s
on top of the basic URL request -- unless the buffer already exists,
in which case it's much faster (albeit still twice as slow as the
other options).

Presumably this could be improved?

If I benchmark-progn the final (funcall func url) in browse-url-emacs
I can see that this is where all the time is spent.  func is set to
`find-file-other-window'; so this is equivalent:

(benchmark-run
     (save-selected-window
       (let ((file-name-handler-alist
	     (cons (cons url-handler-regexp 'url-file-handler)
		   file-name-handler-alist)))
	(find-file-noselect "http://www.example.com")))
   (kill-buffer "www.example.com"))

If the buffer already existed, *Messages* says:
Contacting host: www.example.com:80
(0.408067329 0 0.0)

If the buffer did not already exist, *Messages* says:
Contacting host: www.example.com:80 [2 times]
File exists, but cannot be read
(2.617302471 0 0.0)

(The "[2 times]" is not on account of a previous test;
they are both generated by this single call.)


Benchmarking the end of `find-file-noselect' like so:

	  (benchmark-progn
	    (find-file-noselect-1 buf filename nowarn
				  rawfile truename number))

Gives me:

Elapsed time: 1.876737s (0.057295s in 1 GCs) ;; find-file-noselect-1
(2.680159853 1 0.057295379000000146)         ;; the overall 
benchmark-run

And that's as far as I've gone.

I can reproduce this, too.  I think it's likely that the delay is coming
from the error message (which is a misleading error message).  There's
probably a "sleep-for 2" after displaying the error message?

There's a bug report in debbugs somewhere about fixing the error
message, but I can't find it now.

Perhaps https://debbugs.gnu.org/cgi/bugreport.cgi?bug=42431 ?

There are also a handful of other hits at:

True, `after-find-file' does this:

  (or not-serious (sit-for 1 t))

And indeed that accounts for 1s of the ~2.5s delay; so this is
a significant factor, yet seemingly not the only issue.

With that commented out I now get:

Elapsed time: 0.835925s (0.039518s in 1 GCs) ;; find-⁠file-⁠noselect-⁠1
(1.7317769889999999 1 0.03951770099999996)   ;; the overall 
benchmark-run

Instead of the former:

Elapsed time: 1.876737s (0.057295s in 1 GCs) ;; find-⁠file-⁠noselect-⁠1
(2.680159853 1 0.057295379000000146)         ;; the overall

Yes, that's the one I was thinking about, and it was apparently fixed at
the time?  But this looks like pretty much the same problem, but with a
different code path...

Perhaps there's something else that also wants to sleep a bit after a
file error...  In any case, I think the real fix is to not signal an
error here, because that's wrong.

I haven't looked at this code in a while, though.

With that commented out, I tried to do some profiling like this:

(progn
   (profiler-start 'cpu)
   (browse-url-emacs "http://www.example.com")
   (profiler-report)
   (profiler-stop)
   (profiler-reset)
   (kill-buffer "www.example.com"))

The results were perplexing in their variability -- all I can
suggest is that you run that code multiple times, and C-u RET
to expand the full profile after each run, and see whether you
also observe a variety of fairly different outcomes.

Here's one example where we can see `url-retrieve-synchronously'
being called 4 times; but other times it was called 2-3 times,
and the profile looked rather different.

           10  30%    Automatic GC



I'm not very familiar with the ins and outs of these code paths,
but my first impression is that we've initiated an operation which
needs to deal with a particular URL and if we were to make a high-
level binding to indicate that we were doing this, we could then
cache and re-use the results of those network requests for the
extent of that binding.

3 of the 4 `url-retrieve-synchronously' calls above are from
`url-http-head'; twice on account of `url-file-exists-p', and another
from `url-file-attributes'.

I see the following in the code:

(defun url-http-head (url)
   (let ((url-request-method "HEAD")
	(url-request-data nil))
     (url-retrieve-synchronously url)))

(defun url-http-file-exists-p (url)
   (let ((buffer (url-http-head url)))
     ...))

(defalias 'url-http-file-readable-p 'url-http-file-exists-p)

(defun url-http-head-file-attributes (url &optional _id-format)
   (let ((buffer (url-http-head url)))
     ...))

(defun url-http-file-attributes (url &optional id-format)
   (if (url-dav-supported-p url)
       (url-dav-file-attributes url id-format)
     (url-http-head-file-attributes url id-format)))


In principle, I don't see why we couldn't be re-using the buffer
returned by the first call `url-http-head' in each of the
subsequent calls.

Furthermore, we could *probably* flag the fact that we are 100%
intending to request the entire file later on in the command,
and use that information to just do a GET request instead of a
HEAD request in the first place -- the resulting buffer for which
can then *also* be re-used by the eventual `url-insert-file-contents'
call.

I think `url-http-head' itself should only ever do a HEAD request,
but `url-http-head-file-attributes' and `url-http-file-exists-p'
could conditionally use the full GET buffer.

[excellent analysis elided]

I think the conclusion here is that using the file-name-handler-alist
stuff for this is the absolutely pessimal way to implement
`browse-url-emacs'.

It should be pretty easy to rewrite browse-url-emacs to just call
`url-retrieve-synchronously' explicitly, and then display the resulting
data -- and it should be much, much faster.

Undoubtedly so; but making the existing approach more efficient might
also bring the same benefits to other functionality?

E.g.:

(url-handler-mode 1)

(trace-function 'url-retrieve-synchronously "*trace-output*"
		(lambda () (format " [%s]" url-request-method)))

(find-file "http://www.example.com")

======================================================================
1 -> (url-retrieve-synchronously #s(url "http" nil nil "www.example.com" 
nil "" nil nil t nil t t)) [OPTIONS]
1 <- url-retrieve-synchronously: #<buffer  *http www.example.com:80*> 
[OPTIONS]
======================================================================
1 -> (url-retrieve-synchronously #s(url "http" nil nil "www.example.com" 
nil "" nil nil t nil t nil)) [HEAD]

[HEAD]
======================================================================

That's true, but I kinda feel that this stuff is something that nobody
uses -- it's a fun trick, but you can't do much with it.  That is, you
can load "http://www.example.com" as a file, but you can't save it, so...

It's a fun toy and a demonstration of how you can hook into the Emacs
file machinery.  But if you're writing code that's actually going to be
used (like browse-url-emacs), it's the worst way.

I've now fixed the spurious error message in the middle of this, so it
should be faster now.

It's still inefficient, but I'm not sure that it's worth fixing...
