Intel C++ Compiler Netrunner 50% faster in average.!!!

So wide i know is the Intel C++ Compiler free for Linux.

Switching any Linux distro from the open source GCC complier to a closed source proprietary commercial compiler is not going to happen.

There is however a lot of discussion about switching to the CLANG compiler which claims better performance. (http://clang.llvm.org/comparison.html)

BSD is switching to CLANG (http://www.phoronix.com/scan.php?page=news_item&px=MTE4NDQ) but more for licensing reasons than performance.

Here’s a bit more info (http://unix.stackexchange.com/questions/49906/why-is-freebsd-deprecating-gcc-in-favor-of-clang-llvm)
