Anyone here has benchmarked Intel C++ compiler and GCC?

Question

I am not sure whether I should post this question here, because this seems to be a programming-oriented website.

Anyway, I think there must be some gurus here who knows

Answer 1

We use the Intel compiler on our product (DB2), on Linux and Windows IA32/AMD64, and on OS X (i.e. all our Intel platform ports except SunAMD).

I don't know the numbers, but the performance is good enough that we:

• pay for the compiler which I'm told is very expensive.
• live with the 2x times slower build times (primarily due to the time it spends acquiring licenses before it allows itself to run).
