The server has logic to do so lazily, some commands may not be render (overlapping regions etc) In general, all the commands are sent to the client, until the client "pipe" exceeds some limits due to slower network. In this case, the server starts to render partially for the client to reduce bandwidth, the number of commands, and keep latency low enough. But if you have fast enough network (or on localhost), mostly, all the rendering will be done on client side already. _______________________________________________ Spice-devel mailing list Spice-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/spice-devel
