But even in user space it's not a good idea to use SSE2 unless you really need it because it increases the cost of the context switch and costs an exception each time first in a timeslice. P.S.: I was the original poster, but the application wasn't a kernel but I doubt it's a good idea to use SSE2. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=17886
