SCCM 2012 Boost PXE deployments speed.

Hello guys!

I’ve written about this subject before, but I’ve been getting some questions over the holidays about PXE boot and how to improve its performance, change the rate at which it deploys images etc …

So to give yourself a little more flexibility, you can use following steps below.

From the distribution point (where you enabled PXE) complete the following

  1. Open regedit and locate HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SMS\DP
  2. Add a QWORD value (for 64bit Server OS , I’m using Server 2012) and call it RamDiskTFTPBlockSize
  3. Give it a Hexadecimal value of  “4000” or a decimal value of “16384” for example,

Try a deployment from the distribution point where the changes were made, and you’ll notice a speed difference!

NOTE: As always, be sure that you don’t over indulge, it can have a degrading affect on network traffic.
