Slow image deployment download since SCCM 2012 R2 upgrade

Recommended Posts

I am using ESXi 5.5 to host SCCM 2012 R2 server. Laptops that I apply image to is Lenovo T431S, which was very fast inded with Winpe 4.0. As some have stated above 4.0 is still fast after upgrade to SCCM 2012R2. This makes me beleive the problem lies within Winpe 5.0.

Just after checking this out and same problem also:

Hyper-V 2012, DP on Server 2012......chronic download speeds even testing on a VM that sits on the same Virtual network switch as the DP.

 

It seems fine if you specify to Access all content from DP which is the setting I use but just wanted to check this out and it seems to be a problem that has just arose from the upgrade to R2 as this has been tested before on SCCM Sp1 without any issues.

 

50% downloaded and 5 mins have went past on a 2gb wim.

ok the problem has been identified apparently (on a separate list) and here's what they said

 

we have identified root cause and Sustained Engineering is going to start working on a hotfix. Basically the block size for how often the Task Sequence Progress bar updated was changed and it was updating much more frequently, causing the download the slow down significantly. I’ll provide more details as I have them. Engineers are working on to create a Hotfix and it make take few weeks before we can see the hotfix

 

 

so i guess a hotfix is coming

 

cheers

I've never used the "Access all content from DP" option before, I've always used download and run locally but i was testing it today and found the same thing, much quicker.....but would i be right in thinking that this change is the reason some of my packages that run batch scripts didn't work? Two of which execute .bat files with multiple lines. I assume that running them in a "remote run" scenario causes them to execute with a \\server\share based path for the executable rather than a local drive letter which is why they'd failed?

 

.....I spent ages trying to work out why they kept getting an error and I've eventually come to that conclusion, can someone confirm if it sounds correct?
