In case anybody is interested, here it is thus under Debian Etch :
uname -a :
Linux arthur 2.6.18-6-686 #1 SMP Thu May 8 07:34:27 UTC 2008 i686 GNU/Linux
root@arthur:~# /usr/sbin/apache2ctl -V
Server version: Apache/2.2.3
Server built: Jan 27 2008 18:13:21
Server's Module Magic Number: 20051115:3
Server loaded: APR 1.2.7, APR-Util 1.2.7
Compiled using: APR 1.2.7, APR-Util 1.2.7
Architecture: 32-bit
Server MPM: Prefork
threaded: no
forked: yes (variable process count)
Server compiled with....
-D APACHE_MPM_DIR="server/mpm/prefork"
-D APR_HAVE_IPV6 (IPv4-mapped addresses enabled)
-D SUEXEC_BIN="/usr/lib/apache2/suexec"
-D DEFAULT_PIDLOG="/var/run/"
-D DEFAULT_SCOREBOARD="logs/apache_runtime_status"
-D DEFAULT_LOCKFILE="/var/run/apache2/accept.lock"
-D DEFAULT_ERRORLOG="logs/error_log"
-D AP_TYPES_CONFIG_FILE="/etc/apache2/mime.types"
-D SERVER_CONFIG_FILE="/etc/apache2/apache2.conf"

prefork thus.
I'll re-read the previous posts now, about what's better, faster,
sexier, etc..
