I'm using pjsua sample application(SVN 2913) on 270MHZ ARM926EJ-S with Linux 2.6.10. The pjsip is built with arm gcc 4.2. PCMU is used during dialog. If -echo-tail =0, only about 1% cpu is consumed by pjsua. If -echo-tail=20, about 50% cpu is consumed. If -echo-tail=60, about 100% cpu is consumed. I reviewed the report "PJMEDIA Performance Measurement"(http://trac.pjsip.org/repos/wiki/PJMEDIA-MIPS). This report gives much better result than mine on ARM . For 8KHZ echo canceller 100ms tail len, it consumes only about 30% cpu. Where is the problem? Best Regards. -------------- next part -------------- An HTML attachment was scrubbed...
