#24 The continuousupdates (CU) parameter it is not working...

[Vasilica Petcu]

In the java TurboVnc Viewer, disabling the continuousupdates (CU parameter) doesn't seam to work.

When I try to do that, log doesn't say "Enabling continuous updates" any more... but has no efect in practice. With CU parameter false, the transfer rate suppose to be lower... at least I think it suppose to be...

Thank you,

Whether or not the RFB flow control extensions have any effect depends on the network. Without the flow control extensions, the rate at which the server can send updates to the client will be limited to 1 / (Ping time), since the server will have to wait for a request from the client before sending a new update, and the client will not send a new request until it receives an update. If you're running on a low-latency network, then you may never run into a situation in which the latency is limiting performance, so the flow control extensions may not have any visible effect. But let's say you're running on a 10 Mbit broadband connection with 100 ms of latency. Using low-quality JPEG, TurboVNC could normally transmit something like 20 Mpixels/second over this connection, but without the flow control extensions, it will be limited to 10 updates/second, regardless of how big or small the updates are.
