I wonder if its worth setting the performance level inside the “State Restore” step as well … for MDT that is
From: [email protected] [mailto:[email protected]] On Behalf Of Michael Niehaus Sent: April 7, 2015 1:04 PM To: [email protected] Subject: RE: [MDT-OSD] Speeding up OSD process No change would be the expected result with a VM – power settings don’t matter there. I would expect the changes to be most noticeable with more recent processors that are more aggressive with power management. The improvements would be entirely due to the CPU speed increase from the “high performance” power profile. That benefits any CPU-intensive process, including WIM decompression and a few other operations that happen during first boot of the OS.

Then I added it to my main task sequence, and timed an OSD without the changes, and then with the changes. Unfortunately, there was virtually no difference.

Is it the decompressing of the wim that receives the speed buff ?

However, it shouldn’t speed up disks, memory, network, or the CPU within virtual machines. -k From: [email protected]<mailto:[email protected]> [mailto:[email protected]] On Behalf Of Miller, Todd Sent: Friday, April 3, 2015 11:07 AM To: [email protected]<mailto:[email protected]> Subject: [MDT-OSD] Speeding up OSD process There is an intriguing post on The Deployment Guys about setting the powercfg to High Performance during OSD that claims to improve writing the WIM to disk performance by 20%-50%. I can’t wait to try it, and I thought others might be interested too. If you implement it, please report back on your time savings and I will do the same. http://blogs.technet.com/b/deploymentguys/archive/2015/03/27/reducing-windows-deployment-time-using-power-management.aspx I got notified of this post on account of following Ben Hunter on the twitter. ________________________________ Notice: This UI Health Care e-mail (including attachments) is covered by the Electronic Communications Privacy Act, 18 U.S.C. 2510-2521, is confidential and may be legally privileged.
