Please list any experience/knowledge you've had with Speex on the following hardware, including model, minimum speed required for real-time or other observations. When providing benchmarks, please specify:

CPU speed
Speex version
Sampling rate (narrowband vs wideband)
Bit-rate
Complexity setting
Any other option that isn't the default
Compiler (and version)

x86

SSE optimisations (intrinsics)

Power

No Altivec support yet

ARM

Port with gcc inline assembly.

Performance results for Cirrus Logic EDB9315A @ 200MHz

Tests were run with following configuration:

Speex svn rev.13928
fixed point (though this CPU have hardware floating-point, we were interested in fixed point operation at that moment).
Narrow-Band
complexity set either to defailt or to minimum value, I do not recall exactly now :( But I think results will not differ considerably.
no DTX
no preprocessing, just bare encoding/decoding

Speex NB performance on Cirrus EDB9315A @ 200MHz
	mode=2	mode=3	mode=4	mode=5	mode=6	mode=7	mode=8
encoding	3.7ms	3.3ms	4.5ms	3.7ms	5.8ms	4.7ms	3.2ms

Please, note, that these values may be inaccurate and may be different in your system. E.g. different version of gcc produce different results. These values should rather give you rough idea on how Speex performance looks like.

Someone did some optimisations for that but it never got fully merged.
