2.4.19-rmap15a [5] 318.1 22 1 35 4.40

slightly faster than rmap15 here

2.4.19 [1] 132.4 55 2 9 1.83
2.4.19-rmap15 [3] 130.2 55 1 19 1.80
2.4.19-rmap15a [5] 143.7 51 2 6 1.99

slightly slower than rmap15 here

2.4.19 [3] 492.6 14 38 10 6.81
2.4.19-rmap15 [3] 222.9 33 13 9 3.08
2.4.19-rmap15a [5] 209.9 35 12 9 2.90

a little faster than rmap15 here (and a lot faster than vanilla)


read_load:
Kernel [runs] Time CPU% Loads LCPU% Ratio
2.4.19 [2] 134.1 54 14 5 1.85
2.4.19-rmap15 [3] 129.5 56 20 5 1.79
2.4.19-rmap15a [5] 119.0 61 9 4 1.65

a little faster during large reads


list_load:
Kernel [runs] Time CPU% Loads LCPU% Ratio
2.4.19 [1] 89.8 77 1 20 1.24
2.4.19-rmap15 [3] 90.4 76 0 12 1.25
2.4.19-rmap15a [5] 90.8 76 0 12 1.26

mem_load:
Kernel [runs] Time CPU% Loads LCPU% Ratio
2.4.19 [3] 100.0 72 33 3 1.38
2.4.19-rmap15 [3] 105.3 72 37 5 1.46
2.4.19-rmap15a [5] 111.4 66 31 3 1.54

Seems a little slower here. I wonder if it's just because of the artificial
nature of the actual memory load used in the test, or if it's a true slowdown
during periods of memory stress?


These contest benchmarks for rmap15a show only small differences between
rmap15 and rmap15a with more speedups than slowdowns.
