To work out if you use prefork or worker, run:
httpd -V
For example:
Server version: Apache/2.2.9 (Unix)
Server built: Sep 19 2008 10:58:54
Server's Module Magic Number: 20051115:15
Server loaded: APR 1.2.7, APR-Util 1.2.7
Compiled using: APR 1.2.7, APR-Util 1.2.7
Architecture: 64-bit
Server MPM: Prefork
threaded: no
forked: yes (variable process count)
Server compiled with....
-D APACHE_MPM_DIR="server/mpm/prefork"
-D APR_HAS_SENDFILE
-D APR_HAS_MMAP
-D APR_HAVE_IPV6 (IPv4-mapped addresses enabled)
-D APR_USE_FLOCK_SERIALIZE
-D APR_USE_PTHREAD_SERIALIZE
-D SINGLE_LISTEN_UNSERIALIZED_ACCEPT
-D APR_HAS_OTHER_CHILD
-D AP_HAVE_RELIABLE_PIPED_LOGS
-D DYNAMIC_MODULE_LIMIT=128
-D HTTPD_ROOT="/usr"
-D SUEXEC_BIN="/usr/bin/suexec"
-D DEFAULT_PIDLOG="/private/var/run/httpd.pid"
-D DEFAULT_SCOREBOARD="logs/apache_runtime_status"
-D DEFAULT_LOCKFILE="/private/var/run/accept.lock"
-D DEFAULT_ERRORLOG="logs/error_log"
-D AP_TYPES_CONFIG_FILE="/private/etc/apache2/mime.types"
-D SERVER_CONFIG_FILE="/private/etc/apache2/httpd.conf"
I'll comment more later when know about that.
BTW, are you actually using PHP module? If not you should disable it
in Apache as PHP has a high base level memory usage as its
module/shared library is quite big.
