Description:

I have tested php v5.2.10 and v5.3.10 and SVN. icc 10.0 10.1 11.0 11.1 and
centos 5.3 32bit /ubuntu server 9.04 64bit.

18533 nobody 25 0 95032 20m 14m R 33.3 8.0 149:01.55 php-cgi
18534 nobody 25 0 93312 7988 3668 R 33.0 3.0 212:03.38 php-cgi
Reproduce code:
---------------
compiled your php with icc as fastcgi mode:
CFLAGS='-O2 -unroll2 -ip -march=core2 -xT' CXXFLAGS='-O2 -unroll2 -ip
-restrict -fno-implicit-templates -fno-exceptions -fno-rtti -march=core2
-xT' ./configure --prefix=/var/webserver/php
--with-config-file-path=/var/webserver/php/etc
--with-mysql=/var/webserver/mysql
--with-mysqli=/var/webserver/mysql/bin/mysql_config
--with-iconv-dir=/usr/local --with-freetype-dir --with-jpeg-dir
--with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml
--disable-rpath --enable-discard-path --enable-bcmath --enable-shmop
--enable-sysvsem --enable-inline-optimization --with-curl
--with-curlwrappers --enable-mbregex --enable-fastcgi --enable-fpm
--enable-force-cgi-redirect --enable-mbstring --with-gd
--enable-gd-native-ttf --with-openssl --enable-pcntl --enable-sockets
--with-mcrypt --with-mhash --without-pear --disable-debug --disable-ipv6
-march=core2 -xT it's optimizeing for intel core2 cpu.
