Comment (by heleppkes):

 This is not the tracker for x264, please report any performance concerns
 to them.

 Note that much optimization comes from hand-written x86 ASM, which
 required years of development, so the same level of performance cannot be
 expected from a somewhat obscure CPU instruction set.
