Shouldn't we use something like "pmap -d <PID>" instead? I am on lucid with a slightly memory-constrained machine (512MB that used to be plenty enough for jaunty). So this is what I see at the bottom of "pmap -d 3334" (firefox-bin's PID): mapped: 253560K writeable/private: 175508K shared: 988K This is a not-so-old session with only this single tab. I am not really shocked by the 253MB mapped, but by the 175MB. I attach the output of the above command, one can see a lot of [ anon ] mappings, don't know whether this is important, here are all the anon lines mapping at least 1MB:
