[Freeswitch-users] Interpreting "top" output

Wed Mar 5 01:18:03 MSK 2014

somehow the original link got broken:
https://gist.github.com/ssinyagin/9302079

it's a dual-core CPU with hyperthreading (total 4 virtual cores). Either top or mpstat show incorrect information, the only question, why and what is the real load.
