tried to use apt-build to optimize everything
In which case, why not use a source-based distro?
One thing I would like to see more of:
1) measurements of how much time is spent compiling
2) how much faster the programs are than `processor-generic' binaries.
3) how often the system is updated (i.e. how often you compile a program *again*, but in a different version).
... all three investigated *together*.
I imagine that for average desktop home usage (i.e. keeping your programs reasonably up to date), it doesn't pay off. Of course I have no data to back it up.
... just something to think about.
