Latency the Microsoft way...

Here is the Microsoft way to detect latency.

LatencyMon is a nice tool to diagnose issues on the fly, but should you wish to display latency as a report which you can post in the forums, this is probably a better way to get your point across.
 
This is the Windows 8.1 kit, there are versions for earlier operating systems:
http://www.microsoft.com/en-us/download/details.aspx?id=39982

Once you run the installer, it would prompt you to select the tools that you want to download and install.
Select Deployment tools * and Windows performance toolkit and install.

After the installation is done, open command prompt with administrator rights. Press Windows key + X and click Command Prompt (Admin)
 
Now, run this command:
xperf -on latency -stackwalk profile -buffersize 1024 -MaxFile 256 -FileMode Circular && timeout -1 && xperf -d DPC_Interrupt.etl

Now, do a capture for when you face the latency issue (press spacebar).  It should time out after a period of time or press another button.
 
Then type this

xperf -I DPC_Interrupt.etl -a dpcisr > dpc.txt

Then type:
 
notepad dpc.txt


Paste into the forums or whatever...
 
Cheers...

Hmm, where is the one for windows 7 ?
I don't see it.

I only got the performance and assessment pieces and the download is 2.6 GB.
 
Not sure that this is going to be a better solution than LatencyMon.
 
Downloading now.

After uninstalling, Sonar did not work properly until I restarted my computer. I was afraid I was going to have to do a system restore, but that proved not to be necessary. Still, you should think about it before installing this software. It definitely impacted my ability to work in Sonar.

oops

I appreciate knowing about it, Alex. It seems it's more for managing an enterprise of images of Microsoft Software... like where you have 1000 PCs you have to push OSs and Patches to. It's not that it isn't interesting. More that it is a 747 when most folks here need a Cessna. Looks like it might have a bit of a learning curve as well as a big foot print.

Be careful about using stuff like this from Microsoft. I'm not saying this is a bad tool, but...
 
At one point I had the entire Visual Studio stuff, debuggers and so on and I use the Windows LOGO Certification Toolkit for Windows 7 to do some tests.
The Certification tool had something that would capture the entire machine state - Registry and all files on all volumes - let you do an install - and then run again and report ALL the changes between those times.
 
However, this interfered with the installation and registration of some dlls in Sonar X1. It took a while to figure that one out.
 
And uninstalling the Logo Certification toolkit did not uninstall the registry scanning filters that were messing up the Sonar registration.  I had to edit the registry to remove them.
 
Maybe Sonar X1 was not Logo-compliant, but I feel the tool itself is even less compliant.
 
When I upgraded to Windows 8, I abandoned all the extra system tools, debug symbols, etc., etc. I don't regret that decision for a minute. You might not know what sort of system hooks these are adding to capture that sort of data.
 
 

Huh, sadly it looks like M$'s reputation precedes them in these forums... ;)
Anyways..... Looking at my instructions I wonder if Deployment tools and Assessment toolkit is needed now, and just install performance tools.
Weird though I haven't had any issues so far.... Anyways as I say I prefer latency monitor most of the time, it's just another tool.

Anyway I beg to differer, with the latest tools Microsoft has quite nicely avoided bloat and DLL hell, even with Visual studio 2013 it seems. And nope you wouldn't catch me dead with Visual Studio on my DAW PC, that is on my pro development laptop upstairs ;)
