Speex enc high cpu usage OSSBuild. Intel CPU

[tanmay.ambre]

Hi.
I am using libgstspeex library and encoder to build a gtsreamer application

I found that all my intel Pentium 4 machines consume 15-50 % CPU when I use
speex. Same when I use AAC or any other encoder the CPU consumption is
stable at 0-5 %.

After searching through various posts I found a post (
http://permalink.gmane.org/gmane.comp.audio.compression.speex.devel/6304 ) 
from 2009 which states similar observation to mine. 

It states that I need to build the speex library for fixed point operation
rather than floating point operations for some intel processors.

Has any one else experienced similar problem or is there a straight forward
solution.

I am going to rebuild the speex library to use fixed point as mentioned in
the post as well as the manual.

Is this a correct approach?

Tanmay
