Created attachment 102690 [details] sysprof screenshot of system-wide profile run Running skype on my mother's old Pentium-4 based laptop, I noticed pulseaudio consumes a fairly high share of CPU ressources. As can be seen in the attached sysprof-screenshot, pulseaudio consumes almost half the cycles skype does. However this was a video-call - so skype was not only de- and encoding audio, but also video. Furthermore, pulseaudio consumed almost 3 times the CPU cycles of Xorg required to push the video pixels to the display. System: - Pentium 4, 2.6ghz - Fedora 20 + latest updates - pulseaudio-4.0-13.gitf81e3.fc20.i686 I've seen similar behaviour on my modern (sandy bridge core-i7) x86_64 laptop, where pulseaudio consumes as much CPU cycles just playing sound as mplayer needs to decode and display/output video and audio.
