I managed to roughly duplicate this behaviour on my laptop which is an i7-6600U. In fact the speed difference is more dramatic, 51s for the binary package and about 30s for the "self compiled" version (with -march=native). There is a small improvement (from 59s to 51s on my laptop) in -4 due to using CMAKE_BUILD_TYPE=Release. I'm not sure if further improvements are possible by tweaking buildflags, that will require some more test builds.
