--- Comment #12 from Eero Tamminen <eero.t.tamminen at intel.com> ---
Note: kernel had been scheduling parallel media processes very unevenly (I
think most visible on GT4e SkullCanyon).  This appears to have been fixed
somewhere in early February (and AFAIK didn't happen earlier in 2018). If one
just sums FPS reported by the individual processes together (like is suggested
in first comment use-case), not fully parallel scheduling could distort the
results significantly.
