(note: i'm starting a new thread for this since my original post blaming firefox for system slowdown now seems inaccurate. the problem appears to be more widespread.) the system: an asus g74s, quad-core i7 with 16G of RAM, so i'm fairly confident that physical limitations aren't the problem. to establish a baseline, i'm in gnome 3 with only a couple terminal windows open, no browser. performance is snappy -- when i move the USB mouse, the cursor moves appropriately, nice and crisp. and "top" shows Xorg puttering along, using in the neighbourhood of 5-10%. all in all, everything working just fine. oh, using the 3.15.0-0.rc0.git9.1.fc21.x86_64 kernel as well. now i start a single instance of epiphany, and i have a single tab open on a page of my web site wiki which contains nothing but text -- that is, no gifs, no video, nothing like that. performance still seems fine, but now i go to simply move the epiphany browser window and response just plummets. simply dragging the browser window to a slightly different location is painfully slow and jerky, and Xorg CPU usage jumps to 50%. as soon as the move is over, Xorg CPU usage drops back to normal. slightly different experiment -- just try to resize the browser window by dragging a corner, again horribly slow and Xorg usage briefly jumps to 88%. in fact, just moving the cursor *across* the browser window causes it to slow horribly. and i tried this from a throwaway guest account, same symptoms. (all of this matches what i saw with firefox, which is why i switched browsers, but i see exactly the same problems.) and trying to watch a youtube video is practically futile. i opened up a second epiphany tab and popped over to http://www.youtube.com/watch?v=0bXSeheZLq8. interestingly, while audio seems fine, i'm lucky to get one or two frames per second, the video is that erratic. and while the video is playing, Xorg is up around 90% CPU usage and keyboard response while typing this has a massive time lag. this system has an nvidia chipset, and here's the relevant nouveau-related "lsmod" output: $ lsmod | grep nouveau nouveau 1178761 3 mxm_wmi 12865 1 nouveau i2c_algo_bit 13257 1 nouveau drm_kms_helper 50413 1 nouveau ttm 85373 1 nouveau drm 288814 5 ttm,drm_kms_helper,nouveau i2c_core 38734 6 drm,i2c_i801,drm_kms_helper,i2c_algo_bit,nouveau,videodev wmi 18804 3 mxm_wmi,nouveau,asus_wmi video 19456 2 nouveau,asus_wmi $ i have to think this is something related to nouveau since nothing else seems to explain it. is there some kind of gnome setting i can play with to see if that helps? i'm open to suggestions. rday -- ======================================================================== Robert P.
