Hi, How hard would it be to assign sub-application-granularity "blame" for all the memory used by a full desktop (GNOME+Evolution+Mozilla+OO.org)? Something like: 5M sum of per-app icon theme caching 5M sum of per-app base gtk_init() overhead 10M sum of per-email data in Evolution 7M base evo overhead with no mail loaded 30M sum of all executable pages (libraries and binaries) ... i.e. try to get an idea of where focused optimization could have the most impact on the desktop overall - what percentage of TOTAL memory usage for the whole desktop can be blamed on each optimizable item, with sufficient granularity to be useful.
