I am trying to find concise and complete instructions on how to convert a new installed and configured Sabayon system to Gentoo 'stable' stripped down system with custom kernel compiled with '-mtune=native' and where appropriate with '-O3 -fomit-frame-pointer' compile flags set.
The purpose is to run a custom application which compares and flags identical content in more than 1,000,000's files with file length of a 10Kb to 50Gb. The process completes on fully optimzed Gentoo system without GUI about 5 times faster than on OpenSuse 12.2 and Sabayon with the same hardware.
I tried without success for 2 weeks to install Gentoo with Gnome and Xfce Desktop.
Installing and configuring OpenSuse 12.2 takes about 30 minutes including updates and installing and configuring additional applications, such as 'bind', firewall, etc. with YAST. Sabayon takes more than 1 hour.
Compile times are irrelevant.
Please move this post if this is not the right place.
