System slowdown - plugin-container responsible?
 

Hello, fellow Debianists:

As of yesterday, my testing (current) system has slowed down a whole
lot. I thought it was just the 'net, but that doesn't seem to be the
case. top shows something called plugin-containe (I assume it's
actually 'container', but the column's too small for the last letter)
using anything from 15-20 %CPU, and so I'm thinking it's the culprit.
I could just kill it and see what else breaks :) But does anyone know
who or what owns it, or how I can find out?

Thanks
Patrick

It's an Iceweasel thing. Do a search on 'firefox' and 'plugin-container'.
It's behaviour may be controlled from about:config.

Yes, as Brian says is the wrapper for mozilla based plugins:

http://support.mozilla.com/en-US/kb/What%20is%20plugin-container

Killing firefox/icewasel should stop it or just exiting from a web page
that loads the flash player plugin should also reduce the amount of cpu
cycles that uses.

Hi, if shutting down your browser doesn't change anything, you are
probably hit by the xorg transition. Newer xorg doesn't play nice with
some video drivers (read closed source). I had to downgrade xorg to get
a usable system again... Try to launch glxgears (from package
mesa-utils), if it slows down to only a few fps from time to time
without any huge resources usage peak from any other process, then this
is probably the problem.

Hope it helps.

I think it's a browser problem. I simply disabled plugin-container
(by setting dom.ipc.plugins.enabled to 'false' in about:config) and
restarted Iceweasel. Things are now _less_ sluggish, although not as
fast as I might expect. Now, instead of plugin-container using up 20%
CPU, firefox-bin is using about 30% MEM. I'm thinking of making
Chrome my default browser!

Thanks all for the input.
Patrick

30% memory would indicate you have a quite a few tabs open. Mine on
Lenny is about that with approximately 70 tabs going. CPU is in the
region of 8-10%. Flash adverts can consume a fair bit of CPU so I use
the flashblock extension (testing and unstable has it) to calm things
down.
