You don't seem to be a software developper. For me, turnaround
times are very important, and increasing the compile times by a
factor of more than 2 definitely makes me less productive (and that
factor is from a comparison of gcc 2.95 vs gcc 3.2, icc has compile
times similar to gcc 3.2). Speed of the resulting binary is less
important in the development cycle.

Code speed may be important, but less than you'd expect. How many
people use scripting languages with rather slow interpreters?
How many people use a compiled language, but inefficiently?

Of course, best would be *both*: Fast turnarounds for development,
and then, by changing just one compiler switch, fast code, perhaps
with higher compilation times.

Kind regards,
