The exact target rate does not matter for CPU usage, and it's probably
using 44100 already.

Which resampling algorithm are you using? ("aplay -v -D plughw:0 test.wav")
(The fastest one would be "linear".)

This CPU might be too weak to do real-time resampling without special
assembler optimizations.
