General Development Here's something you probably don't know, but really should - especially if you're a programmer, and especially especially if you're using Intel's compiler. It's a fact that's not widely known, but Intel's compiler deliberately and knowingly cripples performance for non-Intel (AMD/VIA) processors.

Really, when it comes with habits, or less information than needed, small information is worse than having none. And we can miss what is in front of us. So...

To better understand the compiler status let's examine it from different scenario points. This give us a more clear picture, even in absence of other indications, as it allow us to compare and thus to scale the importance of a factor...

Imagine that the compiler:
A - Refuses to work on some CPUs.
B - Makes lousy code, in contrast to be the better one.
C - Uses the best routines available elsewhere as the programmers accept to be compromised or non-competent.

Now Check:
A - Fair... but too disturbing, and everybody complains
B - Unfair... no disturbance, and no complains
C - Fair... no disturbance, better product

I suppose that clears the picture, even to someone unable to evaluate the significance of some facts, and it's significance. Just a try (and an hope)...
