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.
