[asterisk-users] How accurate is show translation?

[Vicky]

I tried it on a intel 3 ghz p4 box and a athlon 3000 768 mb ram  running
vista and host for centos 4 ( vmware ) considering  the load on athlon
running asterisk ( that too under vista plus vmware ) while intel 3 ghz p4 1
GB ram box was sitting idle with centos , there was hardly a 1 ms difference
in show translation on both machines . Besides i just compared my p4's
results to ur D930 results and there is no difference ( infact my g729
results are better than ) .. But this doesnt mean both are same  dual core
cpu's will definitely give much higher number of channel transcoding then
lower p4's . Put both the box under some cpu load by other programs and then
use show translation recalc 30 and you will see performance difference
between them ;)
