I recently completely rebuilt the software stack on my Windows PC (3 year old Dell P3.2 HT), reinstalling XP Pro and everything else. Everything is working well (much better than before...why does it seem that all windows pc's have to be re-cored every 2-3 years? but that is another topic!)

Anyway, I reinstalled Uniwire 1.1 and I cannot get the latency to be 2X the host like before. Before, if Sonar was running at 6ms, Uniwire ran at about 12ms. Always. This is documented math

Now it's like 8-9X instead of 2X. I checked my network card (drivers were reinstalled) and it IS connected to my Gigabit switch and it says it connected at 1GB speed. Nothing about the Receptor setup or the switch has changed. I run them on a private network of fixed IP's just like I always have.

Anyone have a clue what I'm missing here?

Thanks
John

Hi John,

This is just a very wild guess - are there any other devices hooked up to an ethernet bridge/switch? I'm wondering if a slower device is connected, and throttling down the speed for the entire bridge.

If this is your connection scenario, perhaps it would be worth isolating by only connecting receptor with a single cable to the PC. (no other ethernet devices connected to your PC either).

Good luck,

That's actually a very good guess. The reason for the GB switch is that I used to have a 2nd Dell PC and I did the FX teleport thing. But now only the one PC and the Receptor are connected to it, so, as you suggested, I have directly connected to the Receptor and rebooted them both. Same result. 6ms on Sonar...48ms on Receptor! Crap.

Also, I disabled both the Wireless 802.11g card AND the firewire/1394 card for good measure. Same result.

I'm totally stumped on this one. Thanks for the input though.

Hi John,

From what you've reported, it really sounds like the problem is related to your software configuration (and not anything external).

One thing I used to do on my PC was optimize XP settings. Since I did this only once when initially configuring my PC, I've since forgotten all that I did (possibly the same is true for you). You may wish to visit some of the DAW forums, and look at XP tweaks - possibly one of these tweaks will boost your ethernet speeds.

Sorry for lack of any direct answer, this is kindof like spearing fish blindfolded!

Thanks for that link. Last night I optimized services (disabled a bunch) based on another site....had been a while since I had done that too.

Net effect is that now Sonar crashes repeatedly and I'm getting BSOD's. Crap.

That new QuadCore system from ADK Pro Audio is looking pretty good right about now.

Will visit your link and hopefully see what I did wrong. I'm thinking that I turned something off that should not be. Once I get Sonar stable again I'll worry about Uniwire I reckon.

Thanks again,
John

ps. Your spearfishing attempts are better than most peoples "expert advice"!

ok gang, in the interest of the community, and because I'm not afraid to look completely STUPID (which I obviously am sometimes) I'm going to post the somewhat hilarious solution to my "problem":

You know how when the Uniwire window opens up and finds your receptor, there is that spot in the lower left that tells you the "latency"....well guess what?

IT'S A BLOODY DROP-DOWN LIST!!!!

For some reason, in the past on my setup it always defaulted to the lowest latency setting. When it stopped doing that I had no idea it was a "choice". I though 48ms was the best it could do. Now I see that I can always choose the "best latency" setting (2X your host setting).

Am I a dork or what?

John

yep. In my line of work (Java programmer by day) we call this the PBKAC syndrome ("problem between keyboard and chair").

I would have thought in the Java world, this would be 'Feature Creep' (with a slow user adoption).

Glad to hear it was something simple - hope you didn't spend too much time re-installing windows!

We call them 'Picnic' calls.
