https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D203732 --- Comment #8 from Arto Pekkanen <aksyom@gmail.com> --- (In reply to commit-hook from comment #4) Okay, now played the above Youtube test video with Firefox without Pulseaud= io. CPU usage (top, raw cpu %) went down a bit, from 150% to around 100%, but C= PU usage is still high. I've also discovered the problem is not only in the audio, problem also with video. You see, when I play video via Firefox, X.org uses around 50% CPU. T= his means that there is a LOT of data copying going on between Firefox and X.or= g.=20 Honestly, the only way I could get X.org use more than a few percent of CPU during video playback with any media player is to use the obsolete X11 -bac= kend (which apparently copies data and does other horrible things). --=20 You are receiving this mail because: You are the assignee for the bug.=
