Both do not put "-O2" by default.255 === Add Optimization Flags to Your Build === 256 257 Be 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. 257 258 258 259 Adding "-O2" could potentially reduce CPU utilization by 20%.
