I've deployed new(0.8.5) version of socket.io and got significant performance decrease. After rolling back to 0.8.4 performance is back to previous good level.
As i've noticed, the main bottleneck - is sending broadcast message.

Currently, don't know the reason of this issue.
Node.js - 0.4.12, Ubuntu 10.04.
