    238238The recommendation below was based on experimentation on Z10 device. The full result of the experimentation is attached as PDF. The patch to measure CPU is also attached.

     240== Tips == 
    240241=== Tune Resampling Quality === 
    241242 
     
    252253Without resampling, a PCMU call uses 0% CPU!

    254 === configure-bb10 script does not enable optimization by default === 
    255  
    256 This applies to PJSIP's {{{configure-bb10}}} script and also the {{{generic-configure-bb10}}} for building OpenCore AMR-NB that is distributed by PJSIP-Demo. Both do not put "-O2" by default. 
     255=== Add Optimization Flags to Your Build === 
     256 
     257Be aware that {{{configure-bb10}}} script does not enable optimization by default. This applies to PJSIP's {{{configure-bb10}}} script and also the {{{generic-configure-bb10}}} for building OpenCore AMR-NB that is distributed by PJSIP-Demo. Both do not put "-O2" by default. 
    257258 
    258259Adding "-O2" could potentially reduce CPU utilization by 20%.
