When compared to emacs 24.5, smartparens is now nearly unusable in emacs
25. I'm not familiar enough with emacs to track down the specific
performance regression, but it appears to be regular expression or
save-excursion related. This is the function that shows up hot on
profiles:
https://github.com/Fuco1/smartparens/blob/1d858a9ec235cef5285503b6bb34be84cc3f5aa3/smartparens.el#L3621-L3646
Here is one such example profile:
- command-execute 20509 84%
- call-interactively 20459 84%
- funcall-interactively 19411 80%
- self-insert-command 10642 43%
- sp--post-self-insert-hook-handler 10642 43%
- sp-insert-pair 5531 22%
- sp--pair-to-insert 5126 21%
- sp--all-pairs-to-insert 5116 21%
- sp--looking-back-p 5107 21%
- sp--looking-back 4620 19%
sp--looking-at 7 0%
#<compiled 0x2b3d647> 4 0%
+ sp--do-action-p 5 0%
sp--strict-regexp-quote 4 0%
+ sp--pair-to-uninsert 405 1%
- sp--all-pairs-to-insert 5111 21%
- sp--looking-back-p 5111 21%
- sp--looking-back 4642 19%
sp--looking-at 3 0%
#<compiled 0x2b3d647> 4 0%
+ file-notify-handle-event 7947 32%
+ newline-and-indent 745 3%
The issue was originally reported here as an issue in smartparens:
https://github.com/Fuco1/smartparens/issues/595
Since it appears to be an emacs regression, I figured I would report it
here as well. Thanks!

To narrow things down, it would be helpful to have a profile from 24.5
(which I understand doesn't have this performance problem?) for
comparison.

All of the profiles in that issue point to smartparens' own functions
as the main sinks of CPU time, so I'm unsure why you think it's an
Emacs regression.

I think the version of smartparens and some kind of recipe starting
from "emacs -Q" is also required, because saying it's unusable doesn't
really tell enough.
As I said, I'm not yet convinced it's an Emacs core problem. I see no
evidence to that effect.
And please don't use elp.el to produce profiles, use profiler.el,
because the latter can profile primitives as well.

I’ve added profiles of both here:
https://gist.github.com/aaronjensen/a1c2b56eac192b0d9cac76b493822070
In this profile, they’re showing pretty much the exact same performance, so
that doesn’t tell us much. I believe the performance degradation is
something that happens over time, and these are fresh runs of emacs. I’ll
have to try and get from 25 next time it slows down on me.
One curious thing is that the emacs 24 profile shows all of the builtins
(let/if/save-excusion) and the emacs 25 profile does not. Is there
something I’m doing wrong that is causing that? I’m using the same
`profiler-start` function.

I’ll work on this. It seems possible that it will be very hard to track
down given the nature—the performance isn’t *always* bad, it just becomes
bad at some point in the session. It’s possible that this is not an emacs
or even a smartparens bug, I mostly opened this in case something stood
out, “Oh, yea we changed the regex engine and…” or something like that.

I don’t even know how to use elp.el, was there some indication that I was?
As I said above, I’m confused by the fact that emacs 25 profiler output is
missing built in functions (Is this what you mean by primitives?)
Thanks!

Thanks.
That rings a bell. The hottest function on these profiles is
sp--looking-back, which calls in a loop sp--looking-at, which does
this:
(defun sp--looking-at (regexp)
"Like `looking-at', but always case sensitive."
(let ((case-fold-search nil))
(looking-at regexp)))
As you will see from bug#18522, binding case-fold-search can be very
expensive, especially if you have a lot of buffers. See
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=18522#201 for a summary
of the findings there. It clearly shows in your profile:
sp--looking-at 171 12%
let 12 0%
As to why you see a slowdown in Emacs 25, I don't know. Maybe you
have more buffers crop up there as the session goes on?
> One curious thing is that the emacs 24 profile shows all of the builtins (let/if/save-excusion) and the emacs 25 profile does not. Is there something I’m doing wrong that is causing that?
Could it be that in Emacs 24 you loaded the library as a .el file, and
in Emacs 25 as a .elc file?
> I’ll work on this. It seems possible that it will be very hard to track down given the nature—the performance isn’t *always* bad, it just becomes bad at some point in the session.
When it becomes bad, count the number of buffers in each session.
Bug#18522 provides some tools for that.

Sorry, my bad. It looked like elp.el output to me.

Interesting, yes this is possible. I switched to Emacs 25 before I started
emacs itself heavily and using window configurations heavily, so it is very
likely that I just end up with a large number of buffers and that’s when
the slowdown happens.
What is the alternative to binding case-fold-search? Could smartparens just
bind it once in a surrounding function? Or is there another way to ensure
that `looking-at` is case sensitive?

I suppose this is possible, I had just started emacs 24 and let it install
all from elpa/melpa (I’m using spacemacs, so it handled all this for me).
Typically it compiles everything, but maybe it hadn’t yet in the session I
was running. I have confirmed that if I eval-buffer smartparens.el, I get
the more detailed profile. That’s useful, thanks.

I couldn’t figure out how to count all_buffers, but I saw (length
(buffer-list)), is that sufficient?

That's one way, yes.

Does smartparens really care about this? Why?

I’d imagine because of things like ruby’s do/end. It wouldn’t want to match
DO/Do/etc.
By the way, I tested without the bind and smartparens doesn’t even show up
on the profile. Thank you very much for helping me track it down.
Would it be worth putting a warning in the docs of `let` for this case? Is
it only case-fold-search or are there other vars that require per buffer
updates to rebind?

Then setting case-fold-search locally in the buffer (with setq-local
and its ilk) should do the trick.

Does this mean that the slow operation is also gone when you do that?

Maybe in the manual.

Any variable which is global by default, but can be local in some
buffers.

Do you mean something like
(let (was-local was-value)
(unwind-protect
(progn
(when (local-variable-p 'case-fold-search)
(setq was-local t
local-value case-fold-search))
(setq-local case-fold-search nil)
do-stuff)
(if was-local
(setq-local case-fold-search was-value)
(kill-local-variable 'case-fold-search))))
?
(Minor modes are generally not expected to leave behind themselves
changes buffer-local values of general-purpose variables).

It seems to be a little better, yes, though it’s hard to tell without
running a long session and opening several buffers. I just opened 200
buffers and it didn’t seem to be enough. I’ll have to wait and see until I
get to it naturally.

Yes, something like that. I admit I didn't study the code well enough
to figure out the details.

Of course.

I have to say that the idea of using the above for changing the value of
case-fold-search instead of let, is surprising for me. Most of the time,
one is using let just for that effect.
The fact that it also changes the default values in all buffers is fine,
for consistency and the principle of least surprise, but paying
N(number-of-buffers) for that seems high.

It only causes trouble if done in the innermost loops of your
program. Otherwise, the cost is almost negligible.

I see. Then I think we should figure out why it's become more expensive
in Emacs 25 (if that is indeed the case).

It isn't yet clear that this is what happened. Can someone time this
in both versions compiled with the same optimization options?

I’m not thinking that this is the case anymore… at least, I don’t have any
evidence to point to that. I still don’t know exactly what state emacs has
to be in for it to be super painfully slow. The fix/workaround, while it
helped, only really shaved off 4ms or so from a typometer avg, which is
significant, but it wasn’t as bad as I had seen it in the slow case, so I’m
probably missing something in the repro.
Any way, I’m happy to consider this bug closed if you all are, though I
think that adding additional caveats to the docs would be wonderful, this
is a particularly nasty/surprising thing.
Thank you all for your help.

Let's wait for a few days, in case you find more interesting data.

With the two patches[1][2] I’ve applied to smartparens, smartparens no
longer has any measurable performance issues on my machine in my testing,
so if there was a regression I’m not going to be able to find it in this
way. I think the most likely story is that I never stuck w/ emacs 24 long
enough w/ my current config to run into the performance issue.
Thank you again for all your assistance.
