osdl hardware, contest benchmark, 2.5.52-mm2 varying the interactive delta:
I've cut it down to the two loads that seem to be affected significantly. The other changes are subtle. id1 is interactive_delta = 1 and so on:
io_load: Kernel [runs] Time CPU% Loads LCPU% Ratio id1 [5] 78.2 108 9 19 2.16 id2 [5] 87.9 96 12 19 2.43 id3 [5] 79.4 105 10 18 2.19 id4 [5] 84.9 109 12 22 2.34 id5 [7] 99.8 94 18 24 2.76 id6 [5] 103.3 104 18 25 2.85 id7 [5] 104.1 89 17 22 2.87
mem_load: Kernel [runs] Time CPU% Loads LCPU% Ratio id1 [3] 78.0 100 34 2 2.15 id2 [5] 94.3 84 35 2 2.60 id3 [5] 92.6 85 32 2 2.56 id4 [5] 65.8 134 39 3 1.82 id5 [5] 63.0 143 38 3 1.74 id6 [5] 69.7 129 38 2 1.92 id7 [5] 90.6 87 32 2 2.50
Seems like io_load likes lower interactive deltas (lower the better?) and mem_load likes high interactive_deltas (sweet spot 5).
