Help understanding Latencymon stats.. What does this mean?
So I've been trying to follow this guide (as well as the optimization guides) at this link http://forum.cakewalk.com/Dropouts-Try-This-m3638234.aspx He talks about running Latencymon for up to an hour to see if any of the fields go over 1000us... and I'm a bit confused by that number "1000us" because look at the numbers I'm getting below after running it for less than a minute: Highest latency on CPU 0: 2.10822 µs Highest latency on CPU 1: 1.80705 µs Highest latency on CPU 2: 0.60235 µs Highest latency on CPU 3: 0.60235 µs Highest latency on CPU 4: 0.60235 µs Highest latency on CPU 5: 0.60235 µs Highest latency on CPU 6: 1.80705 µs Highest latency on CPU 7: 1.50587 µs So when he says "1000us" does he mean 0.01000us or does he mean 1.00000us (which I doubt)? If not, what does he mean? Am I just not understanding decimal or something? People on that thread also mention numbers like 30us and 500us so I guess I'm confused. Thanks

1000 us = 1 ms.
1000 ms = 1 second

On a 3.2GHz machine (for example), each clock pulse is .0003125 microsecond, so those readings are accurate. The reason for seeking things higher, like 1000 µs, is because they can often manifest themselves as audible latency.

Thanks guys. Unfortunately I'm still confused about this "1000us" number against these numbers I'm getting. I'm not sure how to interpret my highest reported latency of 2.10822µs compared to this 1000us number. When he says "1000us" does he mean 0.01000us? Because if so then my numbers look pretty horrible obviously. Feeling pretty dumb.

No, your numbers look fine. None of them are even close to 1000µs. Like you say, your highest latency is 2.10822µs. 1000us can never mean 0.01000us. 1000us (microsecond, or µs) is 1 ms (millisecond), which is 0.001 second. So 2.10822us is 0.00210822 milliseconds, or 0.00000210822 seconds.

You're experiencing confusion because your numbers are so much lower than "bad" numbers would be, thinking you must be looking at it wrong. You're not. Your numbers are excellent. Be happy.
Whether you're experiencing dropouts or not, you can now safely forget about ISRs and DSPs. Even if you are experiencing dropouts, at least you've eliminated these things as being the root of the problem.
 All else is in doubt, so this is the truth I cling to. My Stuff

All of you are awesome and thanks a ton for clearing this up fir me. If it's any consolation to me, grammar has always been my best subject.

We need more grammarians around here. Now, just work on your spilling and the position of editor can be yours! :)
