gst pipeline slower than mencoder

just encoding audio from a52 to mp3. from 2min length title.

time gst-launch dvdreadsrc title=2 ! dvddemux ! a52dec ! audio/x-raw-float !
audioconvert ! lame ! filesink location=test

time mencoder dvd://2 -ovc frameno -oac lavc -o test

mencoder: 2.4s
gst: 7s

same results when copy dvd title to disk first then run encoders

This shows gst is much slower then mencoder
