Hi all,<div><br></div><div>On my netbook with MeeGo OS, pulseadio seems to have some performance issue.</div><div><br></div><div>For example, when use gst-launch to play ogg file and use pulsesink:</div><div> gst-launch filesrc location=/data/1.ogg ! oggdemux ! vorbisdec ! audioconvert ! pulsesink</div>
<div><br></div><div>The gst-launch uses 12% of CPU, and the pulseaudio reaches even 15% of CPU,</div><div>but with direct alsasink, the CPU utilization is 7%. </div><div><br></div><div>I investigate it using sysprof, and figure out that the pa_mainloop_poll in pa_mainloop_run </div>
<div>is the hotspot of pulseaudio server.</div><div><br></div><div>Is there any method to solve the performance issue by tuning pulseaudio ?</div><div><br></div><div>Thanks, Liu</div><div><br></div><div><br></div>
