If you have some more measurements let me know.
?? What version of the Linux kernel headers should be used?
{AJ,UD} The headers from the most recent Linux kernel should be used.
The headers used while compiling the GNU C library and the kernel
binary used when using the library do not need to match. The GNU C
library runs without problems on kernels that are older than the
kernel headers used. The other way round (compiling the GNU C library
with old kernel headers and running on a recent kernel) does not
necessarily work. For example you can't use new kernel features when
using old kernel headers for compiling the GNU C library.
