# cd /usr/src # wget http://downloads.digium.com/pub/telephony/codec_g729/benchg729/x86-32/benchg729-1.0.8-x86_32 # chmod u+x benchg729-1.0.8-x86_32 # ./benchg729-1.0.8-x86_32 ... ... Average for flavor 'athlon-xp' is 1198 milliseconds of CPU time. Average for flavor 'opteron' is 1331 milliseconds of CPU time. Average for flavor 'c3' is 1393 milliseconds of CPU time. Average for flavor 'c3-2' is 1154 milliseconds of CPU time. Recommended flavor for this system is 'pentium3m' with an average of 1119 milliseconds of CPU time.
以我的機器來說,檢測工具建議使用 'pentium3m' 類型。
