Tired of applications with poor or no caching options? Don’t wish to change your PHP Handler for OPCode? Need a boost? Give Mod_Pagespeed a try! Mod_Pagespeed was developed by Google and it acts as an internal proxy which combines your CSS/Javascript/Images then serves them inline and much more. It also makes use of Gzip compression, and can boost your Pagespeed & Yslow grade from an F to an easy A! (true story).
The following is a basic script which will install and configure mod_pagespeed along with mod_deflate (required for gzip compression) on a cPanel server. It is compatible with x86 and x64_64 architectures:
# Mod_Pagespeed installer for CentOS + cPanel

# Released under the GNU v2 License.

if [ -z "$(grep CentOS /etc/redhat-release)" ];then
echo "This installer is provided for a CentOS server." && exit
fi

if [ -z "$(httpd -M 2>&1|grep deflate)" ];then

Also, for those of you who wish to make better use of your RAM, the following commands will load Pagespeed in RAM:
First we make a backup:
cp -pv /etc/fstab /etc/fstab.bak
Now we create 512MB tmpfs entry in /etc/fstab so it gets recreated on boot and mount it:
echo "tmpfs /tmp/mod_pagespeed/cache tmpfs size=512m,mode=0775,uid=nobody,gid=nobody 0 0" >> /etc/fstab
mount -a
