There is a tool which can show L3 cache usage https://www.cpuid.com/softwares/perfmonitor-2.html, it is old as heck, but still works on some (!) configurations. It could work on i7-6700 and help with optimizations. I will also try to use https://github.com/opcm/pcm which supports Intel's cache monitoring technology.

5820k:
with 12 threads L2 hit is 49%, L3 hit is 6%
with 6 threads L2 hit is 54%, L3 hit is 11% but, only 3 cores under load

12 threads: stalled cycles 57% (wtf???), branch hit 99% (don't know what is it), 1.2-1.3 instruction per cycle (don't think it is important as long as it is "medium" value)

tomorrow will compare with 8700k
