[SOLVED] high cpu usage by operapluginwrapper

[tamoneya]

I have been running 64 bit hardy and just recently I switched from firefox 3b5 to opera 9.50 beta. I also have flashplugin-nonfree install. Today I noticed that my computer was running a little sluggish. I ran top and saw that there were two instances of "operapluginwrapper-ia32-libs" that were taking up 30% of my cpu each. I think these are related to making the flash plugin work in 64 bit opera. Does anyone know a way around this problem? Has anyone else run into something similar? I am considering uninstall flashplugin-nonfree if it speeds up my computer but I am curious to know what you guys think.

Well at this point there is a newer version of opera just came out today so might as well be on that.
Here. (http://snapshot.opera.com/unix/snapshot-1951/x86_64-linux/opera_9.50-20080506.2-shared-qt_amd64.deb)

I noticed my flash plugin was at 100% cpu so I uninstalled flashplugin-nonfree and then flash didn't work. I reinstalled via the repo's, installed the new opera .deb and flash still didn't work.

In Opera I went to Tools->Preferences->Advanced, Downloads on the left side. Click on the swf extension and select Edit button.

When I went here the Use plug-in was selected but had the plugin as /usr/lib/mozilla/plugins/flashplugin-alternative.so

I changed it to /usr/lib/flashplugin-nonfree/libflashplayer.so

restarted opera. Flash still didn't work. Then I did an rm /usr/lib/mozilla/plugins/flashplugin-alternative.so hence removing the other plugin altogether. Restart opera again. Now flash works again. Ran top. Now instead of 100% cpu it fluctuats between 20-40% but only when I have a site open that is actively playing flash. When I navigate away from a flash site the opera plugin wrapper drops off the charts. This is acceptable to me as long as it only uses cpu when actively playing flash.

Thanks for the help. I didn't realize they had another build up. I wil try what you recommened and report back here if it works.

Thanks

EDIT: Like always the Ubuntu Forums never disappoint. I was honestly expecting people to say that my only option was to not use flash anymore. Worked perfectly.

so before it was taking 30% all the time and now it behaves as it does on my system for you (ie 30% only when using flash site)? Or is it taking less than 30% now? I'm just trying to quantify normal behavior of it so I know.

[tamoneya]

it used to be running two processes both at 30% 24/7. Now it is running one at 17-18% while playing a youtube video. Once I close that tab it fall off of top. Opera itself is running at about 2%.

after some more intensive testing it seems like the problem is not fully fixed. It seems like everyonce and a while the operapluginwrapper gets "lost" and opera spawns another one. The problem is that the lost one then goes and eats up a bunch of the CPU. I was viewing some youtube videos and I had top going on my other screen. I noticed that I had one operapluginwrapper process all the way at the top with 99% usage and then another one at 18%. The 18% is the normal one from what I can tell and once I close the youtube window it disappears.

Yea def isn't the best behaving thing. Hopefully its fixed when out of beta I have conky running so if I see the wrapper jump up I'll just kill it.

i think it has more to do with flashplugin-nonfree than opera. I hope that the open sourcing of flash creates an alternative to flashplugin-nonfree.

THANK YOU, worked here!:) I was getting worried i'd have to dump Opera because of this but now it is behaving nicely... Opera 9.51/32 bit

was behaving... 6 pages open, not one of them running any flash and Opera and Operapluginwrap alternately hogging between 30-70% cpu all the time.

I guess this issue is not solved after all:(
