Sometimes. There are many performance increases for C++ programs. The older
libstdc++ shipped with gcc 2.95.x had some serious problems with iostreams
- I've seen it be 3-5 times slower than the 3.1 iostreams at times. The 3.1
inliner and register allocators are somewhat better, but not fantastically
so.

I don't do much of anything that would notice relatively minor kernel
performance changes either way.
