I have noticed two related issues. First, under 2.6.3 it averages about 90MB[2] anon memory, and 30MB with the -mm4 vm (the rest is in swap cache). This could balance out on the normal non-idle week-day load though... Second the -mm4 vm, there is a lot more swapping[3] going on during the daily updatedb, and backup runs that are performed on this machine. I'd have to call this second issue a regression, but I want to run it a couple more days to see if it gets any better (unless you agree of course).
