View Full Version : Revisiting Latency

06-02-2004, 09:18 AM
I've been using netTunes for a while now, over AirPort between my iBook and my desktop G4, and have been very happy with it. But just in the last week or so, latency has suddenly become a problem. Prior to that, there was no significant latency at all. Now, even with display quality at its lowest setting, there is a several second delay between clicking in the window and seeing a result on the screen. This delay makes actions like scrolling nearly impossible.

I can tell that the latency is not in sending data from the laptop to the desktop, because actions like pausing take effect almost immediately (though the display takes several seconds to reflect the change). Using Konfabulator's CPU Monitor, I can verify that the CPU is not even close to being maxed out, so that shouldn't be the problem either. I checked the older thread on latency here, but didn't find any additional information that seemed to be of help.

The fact that this came up very suddenly suggests that I installed something that is interfering. Are there any known software conflicts between netTunes and any other software?

I'm not aware of any software that conflicts with netTunes, but that doesn't mean there isn't any.

Clicks aren't terribly "data intensive", so the fact that a click occurs quickly may just mean that it's not enough data to notice that things aren't working well.

There are a few things I'd suggest:

- Since you're working on AirPort, try power cycling your AirPort base station (and, I'd suggest, restarting all the computers attached to it). It's possible that there's a progressive problem in the base station that's causing a problem.

- Similarly, if you've got some routers or switches involved there, power cycle them.

- If that doesn't help, it's possible that you're getting significant interference on your wireless: did you add any new phones to your house or anything like that? Try using the "automatic" setting in the AirPort Base Station admin utility to adjust the base to a clear channel.

That's at least a place to get started: let me know if it helps.
