[Speex-dev] Ask about arm-asm perfomance

[Jean-Marc Valin]

Hi,

As it is, the arm inline assembly is mostly experimental and doesn't provide
that much improvement. If you really care about performance, you should
optimize at the function level (or at least at the loop level). Otherwise,
don't bother.
