I use gkrellm to monitor (casually) whats happening w/ my machine. Lately I've had periods where the system load gets quite high (20) While cpu usage and disk activity are normal (~10%)
This causes excruciatingly slow screen re-draws, kicker responding weeks after I've moused the bottom of the screen, etc.

KDE System Guard will provide you with that info. Click twice on column head 'System%' and highest usage will rise to the top. There is a decent help-file for it. -- Patrick Shanahan Please avoid TOFU and trim >quotes< http://wahoo.no-ip.org Registered Linux User #207535 icq#173753138 @ http://counter.li.org Linux, a continuous *learning* experience

Click twice on > column head 'System%' and highest usage will rise to the top. My system% usage is low (around 10%) as is the user% in these instances, what is High is System Load, (as shown by xosview, and KDE System Guard's system load tab.) The graphs in KDE System Guard are able to show System Load average but I haven't found a setting in the Process Table section which will show me what is creating high system load when my cpu and disk usage are low. Christopher Mahmood suggested an I/O bottleneck, I've got reasonably fast disks and dma enabled on them but I'll check w/ top the next time I save my konq bookmarks, this is one action that I know causes my symptoms.

That's usually an indication of an I/O bottle neck (e.g., a slow disk). Check with top to see if there are a lot of processes in the 'D' state and, if so, you might want to consider getting faster disks. top allows you to signal processes as well. -- -ckm

System load is a system statistic. It is the number of processes in state "runnable", "running" or "uninterruptible" (meaning they're hanging somewhere inside the kernel), averaged over a period of time. If you don't have several small tasks running repeatedly, then the system load is probably caused by the third number, the processes hanging inside the kernel. Those could be caused by almost anything, from bugs in the kernel (or kernel drivers) to faulty or extremely slow hardware. Running or runnable processes are marked by "R" in top and ps, uninterruptible by "D"

Thank you Anders for the description of System Load, it becomes much clearer now. I believe the "uninteruptable" process may be what I am experiencing. I suspect the following is the source of my problem (although I haven't tested it yet). I have numerous konq instances open, each w/ 4or 5 tabs. When I add a bookmark (to my enormousley large and unmaintained bookmarks file) this info needs to be passed to all the instances of konq. I suppose that this "should" be considered an "uninteruptable" task.
