no flame war please, i appreciate Your work :-)
If you add "IMHO" to your statements, i will accept :-)
I only wanted to point out, that i have different needs than You.
My fastest and my slowest CPU differ by a factor of 1000 (100 000 % !)
in speed. Why should _i_ waste my time to look for 22% ?
As all my computers live inside a machine in a production
environment, the 3 most important items for me are reliability,
reliability and reliability. A major influence on reliability
is the amount of energy consumed, so what i am really interested in
is a gcc-switch, which optimizes to minimum energy per task.
A faster completion of a task only leads to longer idle periods :-)
Just my 2 EuroCents
Please continue to look for 1% speedups, dont feel offenced,
that i dont need them :-)
