[dapper] Memory and CPU usage

I've checked both ksysguard and the gnome system monitor. When running side by side, they give different results. They show the same application using radically different amounts of memory (eg. gnome-system monitor shows mozilla-thunderbird-bin using 62.7MiB but ksysguard shows it using ~265MiB). Also, ksysguard which is the only one of the two which reports CPU utilization reports almost all my applications using 0% of my CPU. These glitches are bizarre and it's quite important for me to know how my system is performing in quantitative terms, which is impossible because of the glitches outlined above. The only time they agree is when some application starts to go rogue and use 100% of my CPU for no apparent reason. Even then they don't agree on the amount of memory it is using, and the CPU utilization ranges from 5% to 10% in ksysguard. I know that application is causing the problem because the moment I kill it the problem goes away. This is a major issue. I would like to know which one I should trust (if either) and if possible, how to fix the problem.
