Michael, the default quality setting of the speex resampler uses a filter 4
times as large as audioresample. If using the quality with the same filter size
speexresample is about 6 times faster than audioresample.

My benchmarks were done with
time gst-launch-0.10 audiotestsrc num-buffers=1000 !
"audio/x-raw-float,rate=44100" ! speexresample ! "audio/x-raw-float,rate=48000"
! fakesink

Also I'm probably doing nothing insane in there ;)
