- From a hardware company's point of view:
- ========================================
-
- 10% is *definitely* interesting.
-
- Even 1% wins are interesting, because if you get enough of them...
-
- Modern microprocessors of comparable price sit in a range of maybe 40%.
- 10% is a significant chunk of your competitive advantage. It's equivalent
- to a few months of hardware development. If you don't go for the
- optimizing compiler, your competitor will.
-
- Moreover, compilers have the advantage of being able to be released
- *between* silicon releases - giving a midlife kicker to your product.
-
-
- On the other hand:
- ==================
-
- I've heard of software companies for which compile time is everything, who
- refuse to add optimizations that will make -O more than twice as slow as
- non-optimizing.
-
- The marketplace takes all kinds.
