Just on Boot (livecds), Comparing to Previous Releases
| 7.10 | 8.04.1 | 8.10 9/30 | |
| 32 bit | 146 | 154.1 | 162.5 |
| 64 bit | 212.9 | 237.6 | 238.4 |
Top 4 Applications on boot and their memory usage 32 vs 64 bit (8.10 9/30)
| Top 4 (Initial Boot) | 32 | 64 |
| nautilus | 17.7 | 22.9 |
| Gnome-system-monitor | 7.7 | 10.9 |
| Gnome-panel | 7.2 | 10.1 |
| python | 5.5 | 9 |
Some Common Applications and their memory usage 32 vs 64 bit (8.10 9/30)
| 32 | 64 | |
| Firefox | 22.7 | 34.7 |
| Gimp | 18.3 | 27.1 |
| OOWriter (.bin) | 17.6 | 24.1 |
| Totem | 12.6 | 15.6 |
| Rhythmbox | 15.6 | 23.8 |
| Total (of those apps) | 118.8 | 189.3 |
All numbers from gnome-system-monitor. Is there any project to track Ubuntu (and it's applications) memory usage/performace over releases? Any interest in creating one?

could somebody do the same with kubuntu? would be interesting to see how kde 4 affects things
Wow! I knew 64 bit applications used some more memory, but these numbers come as quite a surprise to me. Fifty percent more memory for the live cd! That is quite shocking to me.
The kernel's written in C. 64bit pointers are 8 bytes, while 32bit ones are only 4 bytes. Plus, most of GNOME is C as well. It's no surprise that they use in the 1.5x-2x range of memory by comparison.
"Unused RAM is wasted RAM" :)
Even with an awful lot of programs open, my 64bit intrepid does barely make use of my 2G of ram. While Vista (32b) uses half of my memory right after boot without any programs started.
Reducing Memory usage of programs should always be a priority, but should never hurt performance.
