The 1 minute average is 2.37 -- but the 5/15 min averages are over 5 !!!
i.e. we may not see the culprit, nor can we tell if swap was maxed out
when the load was over 5. You could get an idea by watching the LED
indicating disk activity (if your box has such)

> 1951 wes 20 0 535m 128m 14m D 6.0 26.0 15:20.42 firefox-bin
After just 1:05 hrs uptime firefox-bin shows VIRT=RES+SWAP of 535M,
and a CPU TIME+ of 15:20. That's high.
My 10.04 kubuntu is up over 19 days with only(in comparison) 118.33 on firefox.
It was suggested to shut down firefox for testing. However, there have been
cases where some firefox process(es) continue running despite the fact that
the app was shut down. The usual way would be to 'kill PID(s)', but we may
get a cleaner picture faster if you simply reboot, start with a shell running
top (let it settle to get at least a 5 Min average), take a snapshot,
then start other apps, then firefox with increasing Tabs and demands.
We may just learn what everybody is already suspecting -- but knowing
is better than guessing.

Subject: [Eug-lug] slow system
Right now the system is running really slow. I installed AdblockPlus
and that did not seem to make a difference. I installed the gkrellm and
it says that there are two users?, with 290 processes running?
for the top command
