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

The MySQL team posted once that icc gave them about a 10% performanct boost over gcc. I'll try to find the link.

In general I've found that the 'native' compilers perform better than gcc on their respective platforms

edit: I was a little off. Typical gains were 20-30% not 10%. Some narrow edge cases got a doubling of performance. http://www.mysqlperformanceblog.com/files/presentations/LinuxWorld2004-Intel.pdf
