restrictions are put on the generated code to make it relocatable. For
some architectures this is good, for some others it is bad. It could
also be due to some custom patches on the kernel you use (SELinux
maybe?) I'm personally not aware that these give a slowdown but I
could suspect it.
Without any more information on the compiler you use or the kernel I
cannot say anything.
