Performance Win 7 <--> Win 8.1 (Same PC, but Sonar's Performance is different)

Under performance options make sure you optimize "processor scheduling" for programs NOT background services.
Check to see if you are running antivirus (always a good idea to run antivirus, please don't disable it, just make sure you exclude folders relevant to your DAW).


You might think you are up to date with drivers but running this has proven me wrong on many occasions:

This might be very useful to you:

When running please enable show details for all processes.

Don't forget to run windows update everywhere and defrag.
 
Remember occasionally you are swapping performance out for stability (with todays processor power we often have the luxury to use it elsewhere when it is useful).

A myth, keep the defaults is my advise: http://forum.cakewalk.com/Priority-Programs-vs-Background-Services-m2303789.aspx
 

The DPC  Latency Checker is invalid for Win 8 (unless they have finally published the new compatible version in the last couple of days). 
 
I don't know how to compare but I don't really see any difference between Win 7 64 bit/Sonar X3 and Win 8.1 64 bit/Sonar X3.  That is on the same hardware with a dual boot system (i7 3770 CPU, 16GB RAM).  I'm seriously considering moving my "production" to 8.1.  I've been checking all my add-ons, hardware, etc and all of it works in 8.1.
 
 

 
Something curious : when i check my system (Win 7 / 64) with DPC (dpclat.exe), it indicates ther is no problem for audio,
but when i run  Latencymon it indicates a problem (hard pagefault).

Hi again:)
 
OK Latency Mon now is very different (I've stopped some services)
Win 7  1. very low and stable 1-5 bulks 2. 3 bulks very stable  3. not visible 4. 3 bulks stable 5. 5 bulks stable 6. fully in red
Win 8.1 1. very unstable from 1 to about 17 bulks 2. 16 bulks stable 3 not visible 4. 3 bulks 4. 5 bulks 6. fully in red
highest DPC Routine Win 7 266,043542 Win 8 197, 031480
 
Don't know what to do with it, the Jumps of the first line is not good I think....what do you mean?
Thanks;)

Hi there:)
How can I insert Images here, it's just possible to insert a link to an image....
 
Thanks
 

No Pictures:(

I was able to see the screen shots, by selecting the text of the link, right-clicking on it, then clicking on the 'Go to .....' in the drop-down (.... is the link).  This worked for both links.
 
I am, though, a bit confused, and please forgive my ignorance on some of this.
 
In your Windows 7 screen shot, it looks like your DPC latency is 180 us (little fuzzy on the screen, but that's what it looked like to me)
 
In your Windows 8 screen shot, it looks like your DPC latency is 137 us.
 
So, it looks like Windows 8 is performing with a lower detected DPC Latency.

Thanks Keith for this.
 
I'm wondering if I haven't discovered a problem on my system.  I seem to have two drivers per channels 0-5, one of each which has DMA enabled, the other not, then channel 6 no and channel 7 yes.
 

 
Can you or anybody else shed some light on this ?  I get the impression I have two sets installed, one from Intel and one from Microsoft.
 
Is this a problem ?  If so, how do I get rid of the microsoft set ?

I'm wondering if I haven't discovered a problem on my system.  I seem to have two drivers per channels 0-5, one of each which has DMA enabled, the other not, then channel 6 no and channel 7 yes.

After further review, and to close this issue in case anyone finds a similar situation when looking at their SATA controllers...
 
My system has 1 SSD, 3 HDDs and 2 optical drives.  These are handled by the X79 controller.
The system also has 2 (pseudo) SATA III ports provided by a Marvell chip.  I don't use these ports and even though I've disabled them in the BIOS, Windows somehow sees the chip and, since all six ports are taken up on the X79 controller, goes ahead and installs a generic SATA controller with 8 channels and puts the Marvell on the 8th.
 
With some trepidation, I gradually deactivated all the non-DMA channels, then the generic SATA controller (rebooting after each step).  I then had only the six X79 channels 0-5 showing in the devices list.  Everything continued to work so I uninstalled the generic controller.  On reboot Windows goes and reinstalls the generic controller with all 8 channels (the extra 0-7) and puts the Marvell chip on channel 7.
 
So I've just deactivated the generic controller without removing it and my channel list now shows only channels 0-5 off the X79 controller.
 

You can also go to http://www.intel.com/p/en_US/support/detect and update from them automatically (I recommend using Internet Explorer to run it). That way you can check if a) A system scan recognizes WHAT you have and b) update any chipset drivers

I tell you, WIN8 is THE DEVIL!
