Slow emacsclient after some time

Slow emacsclient after some time

Hello world,

I currently use emacs like this:

alias e='emacsclient -a "" -c'

e /path/to/myfile.c


which means that *the first time only*, emacs is started as a daemon. Then
emacsclient is called.

But after a while (maybe after opening about 10 files, I'm not exactly sure
the number of opened files matters), then calling emacsclient with a new
file is *slow*.

Actually the frame is instantly created usually on *scratch* or on the last
file I've edited, but opening the new file and put it in the current buffer
takes about 3-4 seconds.

I also tried emacsclient -t, but this does not change anything, still slow.

What could take so long to load with emacsclient ? Even using emacs without
server mode is fastest.

FYI, I use emacs without X

It may be because I use emacsclient within tmux :/

I use emacsclient with tmux too and its even faster than with X11.

Thanks for the feedback, it helped me figuring it out.
I tried on another linux distrib, and I was able to reproduce the
issue with the same tmux configuration.
Disabling this resolved everything:
-set -g default-terminal "xterm"
+#set -g default-terminal "xterm"

Cheers,

For what it is worth, I use emacsclient with screen with the equivalent
configuration.

  term xterm

I do not see any slowness.  Maybe it is worth reporting this bug to the
tmux bug tracker?

Hum actually I used to set it to xterm cause I needed xterm key
bindings (M-up, M-down, M-right, M-left) but in the tmux manual it is
said:

"default-terminal terminal
                     Set the default terminal for new windows created
in this session - the default value of the TERM environment variable.
For tmux to work correctly, this must be set to ‘screen’ or a
derivative of it."

I finally figured out how to get meta + arrow key bindings working
with my emacs whatever the TERM is, so I set it to screen-256color
which fixes the slowness.

If you do not mind sharing, I would be interested in this solution.  I
also set term to xterm for flow control and better meta key support for
fullscreen applications in screen.

Sure!
That's the only hack I've found that seems to work well with
xterm/tmux/rxvt-unicode/etc. :

;; Remap escape sequences to correct keybindings
(defun my-term-setup-hook ()
  (define-key function-key-map "\e[1;3A" [M-up])
  (define-key function-key-map "\e[1;3B" [M-down])
  (define-key function-key-map "\e[1;3C" [M-right])
  (define-key function-key-map "\e[1;3D" [M-left])
  (define-key function-key-map "\e[1;5A" [C-up])
  (define-key function-key-map "\e[1;5B" [C-down])
  (define-key function-key-map "\e[1;5C" [C-right])
  (define-key function-key-map "\e[1;5D" [C-left]))
(add-hook 'term-setup-hook 'my-term-setup-hook)

(global-set-key [M-up] 'windmove-up)
(global-set-key [M-down] 'windmove-down)
(global-set-key [M-right] 'windmove-right)
(global-set-key [M-left] 'windmove-left)

I previously had only this:
;; (windmove-default-keybindings 'meta)

Thanks a lot!  I'll try these out.
