Doing some tests I compiled from sources php 5.3.3 with the new suhosin patch and latest apc on Ubuntu 10.04. I did this waiting for the official packages to be available in the Ubuntu repositories. It works great and I discovered something: the memory consumption is lower (including the committed memory) even though the compiled modules are the same as those installed through apt. Can someone explain this? Is there a difference between the loading of libraries in an apt install versus a manual compilation of the sources?

Maybe you didn't compile in all the same extensions.

This is my apt install from your php-fpm repo:

apt-get install php-pear php5-cgi php5-fpm php5-cli php5-common php5-curl php5-mysql php5-suhosin php-apc php5-gd

And this is my configure script:

./configure \
   --with-config-file-path=/usr/local/lib/php \
   --with-curl \
   --with-pear \
   --with-gd \
   --with-jpeg-dir \
   --with-png-dir \
   --with-zlib \
   --with-xpm-dir \
   --with-freetype-dir \
   --with-t1lib \
   --with-mcrypt \
   --with-mhash \
   --with-mysql \
   --with-mysqli \
   --with-pdo-mysql \
   --with-openssl \
   --with-xmlrpc \
   --with-xsl \
   --with-bz2 \
   --with-gettext \
   --with-fpm-user=www-data \
   --with-fpm-group=www-data \
   --enable-fpm \
   --enable-exif \
   --enable-wddx \
   --enable-zip \
   --enable-bcmath \
   --enable-calendar \
   --enable-ftp \
   --enable-mbstring \
   --enable-soap \
   --enable-sockets \
   --enable-sqlite-utf8 \
   --enable-shmop \
   --enable-dba \
   --enable-sysvmsg \
   --enable-sysvsem \
   --enable-sysvshm

They look the same to me.

And the munin graph:



From the 19th to 23rd is a normal apt install, with 5 children spawned, from 23rd to 25th is compiled from sources with 5 children, and from 25th till present source compiled with 10 children spawned. The jigsaw look is due to the many compiles and stress tests. Normally it is very clean linear graph.

These are the switches I use, taken from the official Ubuntu package:

                --build=$(DEB_BUILD_GNU_TYPE) \
                --host=$(DEB_HOST_GNU_TYPE) \
                --sysconfdir=/etc \
                --mandir=/usr/share/man \
                --disable-debug \
                --with-regex=php \
                --disable-rpath \
                --disable-static \
                --with-pic \
                --with-layout=GNU \
                --with-pear=/usr/share/php \
                --enable-calendar \
                --enable-sysvsem \
                --enable-sysvshm \
                --enable-sysvmsg \
                --enable-bcmath \
                --with-bz2 \
                --enable-ctype \
                --with-db4 \
                --without-gdbm \
                --with-iconv \
                --enable-exif \
                --enable-ftp \
                --with-gettext \
                --enable-mbstring \
                --with-pcre-regex=/usr \
                --enable-shmop \
                --enable-sockets \
                --enable-wddx \
                --with-libxml-dir=/usr \
                --with-zlib \
                --with-kerberos=/usr \
                --with-openssl=/usr \
                --enable-soap \
                --enable-zip \
                --with-mhash=yes \
                --with-exec-dir=/usr/lib/php5/libexec \
                --with-system-tzdata
                --with-config-file-path=/etc/php5/fpm \
                --with-config-file-scan-dir=/etc/php5/fpm/conf.d \
                --sysconfdir=/etc/php5/fpm \
                --localstatedir=/var \
                --enable-fpm \

So there might be some differences.

Thank you for this complete response. I completely forgot about all the patches involved in an official release. So the next question will be, when do you plan on releasing the newer version (just kidding)

Tracking the official package is easiest for me and safest. It's all tested and configured by the official maintainers and if a security patch is released the Ubuntu guys take care of it and I just add back in the sapi/fpm.

So sticking with 5.3.2 is the most stable solution for now.

I'll probably create a testing repo and try it some time though.
