Sometimes i hate company politics. A superb compiler intel c++
they weakened it for K7. Where 5.0.1 compiler was pretty fast
for the superb K7 processors, the 6.0 compiler is deliberatly
doing bad for K7.

intel c++ 6.0 linux KDE3 MP 1.4Ghz run single cpu
is 2.4% slower than msvc 6.0 sp4+processorpack.

Please take into account this is WITH profile information.
msvc is already faster without taking advantage of that.

God, sometimes i hate company politics.

Last so many years msvc did shit litterary regarding to improve
compiler (at least released nearly nothing). In total from
4.5 to 6.0 sp4 procpack it got faster 3% from which the processor
pack is 2%.

Intel c++ which is taking use of all kind of new tricks is
actually 8.5% faster on a P3, but 2.4% slower on a K7.

Sometimes you can dominate because others make major blunders...
...of course intel doesn't sell many compiler versions, so
i understand the math. but sometimes i just hate company politics.
couldn't they make it *equally* fast to the msvc compiler for example?
