Description:
------------
Compiling PHP 4.4.1 into Apache 1.3.34 as a static module results in slow performace. Compiling PHP as an Apache shared module results in expected performance. Here is the relevant compile script for PHP:

Slow performance (static module):
./configure --enable-track-vars --enable-calendar --with-calendar=shared --enable-magic-quotes --enable-trans-sid --enable-ftp --enable-inlin
e-optimization --enable-memory-limit --with-gd --with-zlib --enable-gd-native-tt --with-png-dir --with-openssl --with-curl --enable-bcmath --
with-gettext --with-gmp --with-gd --with-png-dir --with-jpeg-dir --enable-gd-native-ttf --with-mysql=/usr/local/mysql --with-flatfile --with-
gnu-ld --with-mhash --with-mcrypt=/usr/local/lib --with-mysql-dir=/usr/local/mysql --disable-debug --enable-sysvsem --enable-sysvshm --with-apache=../apache_1.3.34

When compiled with the following performance is returned to normal (shared module):

./configure --enable-track-vars --enable-calendar --with-calendar=shared --enable-magic-quotes --enable-trans-sid --enable-ftp --enable-inlin
e-optimization --enable-memory-limit --with-gd --with-zlib --enable-gd-native-tt --with-png-dir --with-openssl --with-curl --enable-bcmath --
with-gettext --with-gmp --with-gd --with-png-dir --with-jpeg-dir --enable-gd-native-ttf --with-mysql=/usr/local/mysql --with-flatfile --with-
gnu-ld --with-mhash --with-mcrypt=/usr/local/lib --with-mysql-dir=/usr/local/mysql --disable-debug --enable-sysvsem --enable-sysvshm --with-a
pxs=/usr/local/apache/bin/apxs

This is on a quad Xeon Dell 6850 with 6GB of memory. Some pages would not load (timeout) and others were approximately 5-10 times slower to load before we moved to PHP as a shared module. Zend optimizer was On.
