https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=218203 --- Comment #4 from Adam Stylinski <kungfujesus06@gmail.com> --- Created attachment 181326 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=181326&action=edit SSE4 implementation Also not as impactful, but definitely measurable is an SSE4 variant. This will actually run on Atoms and a much larger number of other pre-Haswell CPUs. The ZFS On Linux version does 8 padds per loop iteration because they are avoiding the pmovzxdq instruction. This is probably to be compatible with SSSE3 and not require SSE4. -- You are receiving this mail because: You are the assignee for the bug.
