I had similar results with my P3/866, but I was hoping that a faster processor might help to eliminate the occasional
"stumble" I've noticed with Allstar. Especially at the beginning of telemetry or user audio, the audio will sometimes glitch.

It occasionally happens with user audio also. I've not noticed that before when I ran an IRLP or EchoIRLP system.

I'm not sure if it's a USB-related phenomenon, since my previous systems have used analog sound cards, rather than USB fobs.

If nodes with faster processors also have that issue, then I won't spend any more time or energy trying to upgrade my PC, or change to simpleusb, etc. I'll just live with it.

I figured that if the Simpleusb would be less processor-hungry, maybe that would minimize the glitches?

simpleusb?

Can you confirm this?
Might be really easy to get it.
I'll certainly be wanting to do this. :-)

I'm still getting free Pentium III 1U rack serves lately :-)
Which are quite sexy looking and convenient to use for this.
The used 1U Quad Xeons I purchase are going for about $850.  hihi

That's with Top runing at a 20 sample per second rate (which eats some CPU
itself mind you.

This seems to suggest that an 'ol Pentium-3 can cut it for this app.

Somebody please beat me with a baseball bat if I'm wrong!!
