Disabling of Nagle's algorithm in the code

[remotepc]

Hi All,

Can anyone explain why we are disabling the Nagle's algorithm in the code by using setsockopt(sock, IPPROTO_TCP, TCP_NODELAY, (char *)&one, sizeof(one)). What can be the possible disadvantages of not keeping the recommended option of leaving it enabled.

Thanks in advance,
Praveen

Without the tcp_nodelay little updates, get queued.
Normal this should be a good thing, but the problem is that it is not
controled by vnc.

The whole communication between client and server become slow when
the algorithm is enabled. It's better to disable it and make your own queing. Vnc queue little updates (during one update cycle) and send them as block. This way we avoid sending to many little updates (like the
Nagle's algorithm) but still can force it to be send at the end of each update cycle.
