It makes a big big difference on a low memory box. Try running xfce on a 24Mb box with the base 2.4.18, 2.4.18 + rmap12f and 2.4.18+aa. Thats a case where aa definitely loses and without other I/O patches being applied. Its an X11 based workload with a -lot- of shared pages. Both rmap and aa materially outperform 2.4.18 base on this workload (and 2.4.17 blew up with out of memory errors)
