I used Cloud9 for a while. The lag from typing on my keyboard to showing up on my screen became pronounced that I stopped using the service. I was on the free tier. I can see the appeal, but the execution of this service was too poor for me to use. Perhaps in the future I'll try again.

Was this log in terminal or in editor? While there is some lag in terminal because of network latency (same as with normal ssh connection), i never saw any lag in the editor, so it must be some bug triggered by specific browser/os version, did you try contacting their support about this?
