can you show an example of where using even a year-old release of gcc
causes a factor of 2 slowdown? especially for middleware or the kernel.
for actual applications, a factor of 2 is surprising but not unbelievable,
simply because any system will spend most of its time in the application!
kernel and middleware are simply not normally hotspots.
