[sip-comm-dev] on connection use huge amount of CPU


#1

Hi all, more accurate dates :

OpenSuSE 11.3 x64 KDE4 - sip-communicator-1.0-alpha6-nightly.build.3223-linux - audio settings put on portaudio . On an audio call, no video - java takes 45-50%, Xorg - 29-33%, compiz - 10 %, pulseaudio 7% ; then I switched to kwin - java takes 43-47 %, Xorg 30-35%, kwin 23%, pulseaudio - 5-7%; then I switched composite off - java takes 50%, Xorg 30%, metacity 8%, pulseaudio 7%
Switching on and off pulseaudio during audio call did not change the figures.Second scenario again audio call with no video SIP-Communicator's audio setting put on direct access to the audio cards - java takes 40-45%, Xorg - 30%, compiz - 10%, pulseaudio 0%.

In general cases Pulseaudio takes 4-5% CPU on audio player working, and 10-12% on video player working.

That it is.
