High latency in local network

[Idon]

Hi,

I'm using custom sync method instead of built-in PING_PONG:

I send 10 ExtensionRequests from client to server.

Server side:

Code: Select all

	public void handleClientRequest(User player, ISFSObject params) {
		ISFSObject res = new SFSObject();
		long timestamp = new Date().getTime();
		res.putLong("tm", timestamp);
		
		MainExtension parentExt = (MainExtension) getParentExtension();
		parentExt.send(Cmd.SYNC_TIME, res, player);
	}

and then calculate avarage lag.

When I test it locally, i get average lag ~ 8 ms

But when i connect from other comuter in local network area, i get 350 ms latency, though average ping time (windows->cmd->ping) of server host computer is 2 ms.

What may be the problem? Am I doing something wrong?

Thanks in advance,
Ilya

Maybe you are using wireless connections which tend to be slow especially if their signal is not strong enough.
Other reasons could be that you have a slow local network which generates lots of packet fragments. Sounds strange to me but everything is possible.
Without any other info it's quite difficult to guess
