See https://bitbucket.org/multicoreware/x265/issue/143/x265-is-slow-when-it-is-build-with-gcc-51
x265 1.7 has a faulty macro that checks only for GCC mayor >= 4 *and* minor >= 3 used to enable some x86 SIMD, which means the current Arch build is affected as it was built with GCC 5.1.
Commit https://bitbucket.org/multicoreware/x265/commits/98325f22a1bad500e6a0c3372bf8177e81167cae from the stable branch fixes it.

Since ASM is a must for this encoder i recommend rebuilding the package using current stable branch now instead of waiting for 1.8 to be tagged.
This task depends upon
