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).

Yes, seems so. I think this is a good thing for autoregulating 8-)

Exactly my thoughts. Increasingly as the numbers are rolling out it is clear
the defaults seem to be pretty darn good (thanks mingo), but for -ck at least
I wont be able to resist and will autoregulate them once I have a full set of
numbers to play with. I'll get subsets of numbers (too messy to post them all
here) and decide what to use for my ranges. It's my impression so far that
the desktop experience with static numbers can only be improved upon by
dropping the max timeslice to resemble that of the old scheduler. Perhaps a
max timeslice of around 150ms.
