SOLVED SCCM 2107 Taking a long time to load boot image

[tiagobial]

Hi y'all Im having problems with sccm after i update to 2107 the boot image is taking a long time to load the task sequence. Anybody knows why this is happening ? Thank you in advance.

Did you change boot images/update ADK or add more drivers?
Boot images are loaded over the TFTP protocol with handshakes sent back after EVERY 512kb.

If you have a lot of drivers in your image it can be 400Mbyte or more and it becomes slower.
Also distance is a main factor as every Millisecond latency will add delay, waiting for the package handshakes. (a 400Mb boot image results in 800.000 packages and handshakes...)
When at our remotest location 400KM away (~1000km fiber network round trip) a PXE boot will take more than 1½ hour if using the central DP.

I fix it apparently the driver that i was using for the machine was incorrect I upload the right driver and now is working loading fast.

Great! I tried that on HP EliteBook G8 where the driver "did" work but only moved like 10kb/sec.
