Updated it and now I have 0x28, better:
Samples: 8K of event 'cpu/mem-loads/pp', Event count (approx.): 89255
0.75% 1 665 L3 hit [.] arena_run_tree_remove
0.67% 1 602 LFB hit [.] nsSMILAnimationController::DoSample(bool)
0.63% 1 563 Local RAM hit [.] 0x00000000004620c4
0.58% 1 515 Local RAM hit [.] 0x00007f6b278aa7bc
0.54% 1 479 L2 hit [.] XPending
0.33% 1 292 Local RAM hit [.] nsSVGFEMorphologyElement::Filter(nsSVGFilterInstance*, nsTArray<
Will do more tests after lunch,
