Hello. I have successful used GNU Emacs 23.2 that comes with Debian
Squeeze on my I32 machine. Yesterday I decided to download the latest
release from gnu.org, GNU Emacs 23.4. Then I built it with Athena
Toolkit and with -O3 gcc flag. Now Emacs works wonderful except by one
thing: its response time is very high. It takes a half of second to
notice that I press a key. Does anyone know what could be a possible
source of this problem?
Thanks in advance.
PS:
Some useful information:
In GNU Emacs 23.4.1 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
of 2012-02-08 on felix-laptop
Windowing system distributor `The X.Org Foundation', version 11.0.10707000
configured using `configure '--with-x-toolkit=athena' '--with-crt-dir=/usr/lib/i386-linux-gnu' 'CFLAGS=-O3''

I guess the first thing you should do is test it with emacs -Q, which
will run without loading your .emacs file or any other configuration.
If it works fine there, then you should bisect your config file.
Otherwise, the problem lies elsewhere.

System overloaded? What is 'top -o cpu' showing? Could be GNU Emacs 23.4 is looping due to something in the init files.

The same occurs if I start emacs with -Q option. But I noticed
something interesting. If I run a server instance of emacs in X and
then start a client in a text terminal, either xterm or native text
mode, the instance in X yet suffers by delay but the other (in text
terminal) don't. What could be causing this?

According my followup to Aaron Meurer It couldn't be.

I discovered the reason behind this problem. In my home, I often use my
netbook (the machine running GNU Emacs 23.4) connected to a big external
display by VGA output. Today, I used the LVDS screen and guess you what
happened? The problem disappeared. This seems consistent with the problem only
showing up under X frames of Emacs. I'm now wondering why it's
happening only when I connect to the external screen. The only thing I
could think is the stretch transformation rule that I have configured by
xrandr as follow:
xrandr --output LVDS1 --mode 1024x600 --auto --output VGA1 --mode 1024x768 --scale 1x0.78125 --auto
Any idea? It could be a bug in Emacs?

Indeed! It's all "--scale" parameter fault. xrandr's stretch
transformation rule was causing that trouble. Really it isn't a Emacs
bug. I just replaced that call to xrandr with the following:
xrandr --output LVDS1 --off --output VGA1 --mode 1280x1024
Now I'm using a native resolution and disabling the LVDS screen that I
don't need at home. That way, I also won the benefit to improve my
resolution.
It's perfect. My Emacs on a big screen, big resolution, full speed and
full screen (without borders, title bar, scroll bar, menu bar and tool
bar). It isn't the heaven?

I've found that, in general, LCDs do best at their native resolution.
Anything else and they get fuzzy and do strange things.
