Slow response in GNU Emacs 23.4

[Bruno Félix Rezende Ribeiro]

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:
