This seems to be more of a disagreement with -aa1 and -rl2 than -rl2 per se.
Just FYI here's a copy of the SMP results that were in the other thread
entitled "[PATCH] 2.4.20-rmap15a":
io_load:
Kernel [runs] Time CPU% Loads LCPU% Ratio
2.4.19 [5] 162.3 45 28 19 4.48

2.4.20-rl2 [3] 101.8 76 19 22 2.81
io_other:
Kernel [runs] Time CPU% Loads LCPU% Ratio
2.4.19 [5] 62.3 117 11 20 1.72
