I thought this was just a MS problem but its becoming a real pain.
With nothing running ( that Im aware of ) the system just seems slow. I have a constant CPU usage of around 70% and have no idea why.

Everything is up to date but I am at a loss as to where to start looking.
When I check the running processes, I see sytem monitor at about 25% Firefox-bin similar and plugin-container also about 25-30%.

Has a recent update caused any issues with firefox or is something weird just going on with my system?
TIA.

If you will post the details of your computer, that will help.

I.E. processor, amount of RAM etc. Can you post the output of the following
cat /proc/cpuinfo
cat /proc/meminfo
free
dmesg
lspci
please use code tags around the dmesg output :-)

Regards,

Phill.

get a few lines of vmstat 5

might give you an idea on where the waiting is taking place... kernel can take up a lot and not show anything in processes

High CPU usage, nothing running.

based on your screenshot, this is not true.

it is ironic, but the graphical system monitor you are using? it itself uses a huge amount of CPU power to run. you can see this in the system monitor itself. go to processes and sort by CPU%.

take it off your panel & dont run it.

i suggest that you install & use htop instead.

once that is done, we can look at what else we need to do using htop as our tool instead of gnome system monitor.

sort by CPU, see what is towards the top.

there is definitely something running in userspace doing that!

run `top` and see what is at the top of the list. (you can CTRL+C or press Q to exit)


(personally i suspect some sort of indexing critter)

The CPU usage never used to be this high, even when using the graphical interface...something has happened to cause it recently but I do not know what.

Just checked the processes again, highest CPU was 8% with sys monitor, firefox and others mentioned before were 0, Graph still showing 95%!!! and system slow.

Ok, Xorg is the main kernel? the operating system itself?

Sys monitor was CPU hungry...around 20% Xorg is between 5 and 20%. When sys monitor was reporting 95% usage, top was showing a peak of about 45%!

Maybe im just being paranoid. :lolflag:

Just restarted firefox and i have several pages set as my homepage as it were. Some have animations and flash on them. firefox-bin and plugin- container are both around 20-25% each.
Perhaps I will try a different browser and see what happens.

Xorg is what gives us a graphical display, something different than the kernel itself. Xorg talks to the kernel (linux itself is just the kernel, strictly speaking), and the kernel gives Xorg the resources it needs.

flash animations will always be CPU intensive. unfortunately.

Thanks for that.
Have had my home pages set since I first installed ubuntu so am still unsure why this is happening now.

Just tried chromium and sett same pages and cpu usage is down.

Something is going on with firefox.

I'm seeing something similar when viewing flash videos. I think it was Carlee that observed Flash in Linux sucks. It looks like that to me. My desktop is a single AMD athlon 2600+ and it'll run 95%+ CPU usage continuously when streaming flash videos from some sites but not all. Close Firefox and after a few seconds CPU drops to maybe 7%. Chromium seems to be a little better.

good, now we have the problem isolated.

it could have been an addon update.

want to try disabling them all and compare CPU usage?

if that's it, then we can narrow down which addon it is by disabling/enabling them a few at a time and observing results.

Disabled all add ons, firefox running at about 20-25%. plugin container nowhere to be seen.
Strangely, enabling them all again has had little difference.

2.03am here..time to get some shut eye. Will start working on it again in a few hours! Thanks for all the replies so far, appreciate it.

Probably not Firefox. Chrome comes with a bundled flash version and does not use the one from your system. So probably you have a bad plugin installed that is being used by Firefox.

Install and run FLASH-AID (https://addons.mozilla.org/en-US/firefox/addon/161939/) to make sure you have the proper flash plugin installed.


When I check the running processes, I see sytem monitor at about 25% Firefox-bin similar and plugin-container also about 25-30%.

Has a recent update caused any issues with firefox or is something weird just going on with my system?
TIA.

Since Firefox 3.6.4, the flash runs isolated inside a process called plugin-container. This is done to avoid crashing the browser if the plugin crashes.

To reduce CPU usage, install Flashblock (https://addons.mozilla.org/en-US/firefox/addon/433/) and only allow pages were you need to view flash content.

Ablock Plus (https://addons.mozilla.org/en-US/firefox/addon/1865/) might help as well.

Use BarTab (https://addons.mozilla.org/en-US/firefox/addon/67651/) extension. It prevents pages from being loaded until they are needed. So when you start your browser with several pages set as home-page, they don't suck your CPU and memory.

To improve flash performance see Flash Optimization (http://firefox-tutorials.blogspot.com/2010/05/flash-optimization.html).

Thanks for that, will check out the links and install some of the items you mentioned.
It is indeed a flash problem.
Has adobe recently updated their product? I know on windows my son had a new version installed recently. This would possibly be around the same sort of time that I noticed this system running slow or is it just a coincidence?
As I said before, system was fine as it was and watching flash videos etc all seemed to be OK. Now, it just seems to hog the CPU.

When you're done with this, you will say that your cpu usage is just 3-4%. I just removed gnome system monitor and replaced it with htop... My friends here are challenging me to put my drive to maximum use. That would be a challenge... And your htop will respond with just around 50%...
Anyway, thank you guys for providing this support...
