Slow Driver Package Download at OSD with SCCM 2012 R2 SP1

Hi,

i saw very slow Driver Package downloads during OSD today with some Dell Notebook Modells in a brand new SCCM 2012 R2 SP1 Environment. It seems the same like in this blog post:

http://henkhoogendoorn.blogspot.de/2015/03/configmgr-2012-r2-osd-slow-at-driver.html

After i "Allow clients to connect anonymously" as the DP Option the download was faster as you can expect over 1 GB Ethernet. So i assume that's an bug in the SCCM 2012 R2 SP1 Release. Maybe you can share your expierience with that part of OSD too.

Thanks.

Michael

Thanks Jason, you are right to mention the number of files and i will try the option mentioned in the blog.

But only to mention: I had the same driver package for one model (Dell Latitude E7250, arround 800 MB and arround 1000 Files) some days before in the same environment. Difference was: SCCM 2012 R2 CU5 without the option "Allow clients to connect anonymously", and it was fast as the new environment with that option set.

Hi Michael,

Any chance you can get the driver package size (after import)?

I've just imported the same 600MB folder of drivers into both a 2012 CU1 (build 7958) and a 2012 SP1 (build 8239) server. *edit* When referring to package, I mean the source folder where the files are stored post import.

On CU1: Package was 600MB and had 9 subfolders
On SP1: Package was 16GB and had 79 subfolders

It would seem SP1 is creating a copy of the entire directory for each driver...

Thanks,
Chris

Thanks Jason.

Now it is clear why i'm "suprised" about a 5,2 GB driver package for a Dell Precision Modell after the import in SCCM. Originally this package from Dell has arround 1,3 GB.

Jason, any updates on this issue or should we give PSS a call and open up a case? Every driver package I have updated since installing SP1 is exhibiting this same problem. The size of the post-SP1 driver packages are 3 to 4 times the size of the pre-SP1 packages and the number of files is what really blows my mind. My Dell 9020 Win7 driver package went from 1.2GB with 1,600 files to 6.0G with 23,768 files. It takes 45 minutes each for the Prepare and the Download phases to run. I am also fighting a hash error anytime I edit a driver package by either adding or removing a driver after the initial package build. Never had this problem with Pre-SP1. Also adding or removing drivers to the boot images takes so much more time too. Just showing which drivers are currently in the boot image (Driver tab) takes 1 to 2 minutes which used to take just a few seconds.

The Import New Driver Wizard seems to be creating a unique folder for each INF it finds within the source folder location and adding all of the required files for each INF into that folder therefore the size of the package grows by the factor of how many INF files found in the source location. For example, I imported just the audio driver for the Dell 9020 Win7 (x64) which contained 1 folder, 62 files (3 INFs), at a size of 231 MB. After the wizard completed, the package source location had 3 folders, 186 files and a size of 694 MB. You can imagine how many folders are being created for the chipset drivers J. (150 folders at 11.2MB each = 1.68GB just for the Chipset.)

I know there's bug that's been filed but opening a case with CSS is always prudent to raise the visibility level.
