Description
When I open the System Monitor the program itself needs ~13% of the CPU. This isn't bearable, especially if you think that the System Monitor is mostly used when a program hangs and produces 100% CPU workload or so.
The System Monitor shouldn't burden the CPU in any notable amount.

Try "top". That is pretty light weight.

bigdufstuff,
are you suggested that 'top' become the default System Monitor?
taron,
The next release, Hardy (8.04), has a brand new System Monitor. I haven't had much chance to test it, though, so I can't say if it's lighter than the old.

but the System Monitor must have sufficient power to close "outlaw" apps. It must have sufficient CPU.

The System Monitor in Hardy is better. =]

My System Monitor is 0-3%.

My system monitor sits around 13% CPU, on some occasions it even spikes at 90%!!!
Hopefully the new hardy monitor will fix this :]

It doesn't matter if another program is using lots of memory and paging, IF the system monitor is locked in memory so it doesn't page, and IF is has a higher CP?U priority than the misbehaving app. This has not been done though, and I think it definitely should.
As for actual cpu load... I agree, both gnome and KDE's system monitors seem a bit heavy. KDE's a bit less, I think. Also, I'm not sure if KDE's is just like GNOME's, or if it supports alarms, different kinds of charting, etc., like some of the windows monitoring tools. If so, that would justify the usage a bit.
I suspect the main CPU issue is unaccelerated video drivers though, or lack of memory.

Startup of gnome-system-monitor is also all too long.
The system monitor should popup *fast*.

First of all, does that 13% refer to the overall percentage of CPU capacity, or does it refer to the 13% of the CPU /that is in use/ at the moment? The latter is not nearly as bad.
Lowering the CPU usage of the system monitor would also reduce functionality. To lower this number, you'd have to give up things such as the CPU graphs that accompany it. Those graphs are very helpful.
As of now, I'm neutral on this idea. I'm just taking this time to brainstorm =D

actually the system monitor in hardy doesn't fix this obvious issue. i see the same numbers in gutsy and hardy, and it's not a graphic issue, top confirms (and the noise my laptop vent makes) that the gnome system monitor uses WAY too much cpu.
the occasional spikes are the file system updates, setting that to a bigger interval makes the spikes less frequent.
djh2400: 13% of the overall cpu capacity. top and the system monitor that comes with feisty does the SAME job with

taskmgr.exe uses 0-2% CPU and 4164 kB on average...
gnome-system-monitor uses 5-18% CPU and 5.3MB on average...

Much more importantly, system-monitor should have nice: -20

Use conky...it takes less than 2% of cpu resources and very little memory.

The System Monitor in 8.04 shows CPU1 and CPU2 taking turns to hit 95% and then dropping to 5% when viewing the Resources tab. This is with nothing else eating CPU.
If I view Processes tab, both CPUs hover around 8%.

While gnome system monitor is much worse than windows task manager to say it uses so little is an overstatement, it uses from 0.1% or so it's true but as much as 5% on my core duo (I don't run windows any more, whee! Thank you, Ubuntu. Thank you, Mark!)
Anyone who wants to see how much cpu is in use all the time might consider gkrellm. I have it set to 2 updates/sec and it is very lightweight (plug shows my thermal zones, disk/net activity, memory usage, keyboard LEDs, clock with moon phase :)

Present system monitor consumes way toomuch memory and CPU cycles and i agree with the author of this idea. We still need the functionality it has, but it should be less resource hungry.
Gkrellm, conkey and such are good (infact excellent)to display information, but they can not manage process. Perhaps the purpose is slightly different.

This is about bug #187383 in Ubuntu. Please use the bug tracker for bugs, not Brainstorm.
