[gst-devel] How to decrease CPU consumation for audio recording?

[Zhao, Halley]

I have a simple audio recording pipeline as below. To my surprise it consumes CPU as high as a 640x480 video recording. Could it be optimized to use CPU less?
gst-launch alsasrc ! audio/x-raw-int, rate=8000, width=16, depth=16, channel=1 ! queue ! audioconvert ! vorbisenc ! oggmux ! filesink location=test-audio.ogg

on a netbook with ATOM 1.6GHZ, ~90 %CPU.

Thanks in advance.
