i would send one or multiple characters in a specific interval (500 or
1000ms), and only if there are outstanding chars or key actions to send.
This would reduce the traffic if somebody is typing very fast.
And as Ralph suggested some index for ordering would be good. In order
delivery is required according to the RFC, but as we have seen in a
previous discussion its currently a problem on some servers.
