How to make PXE TFTP Boot Faster?

Usually it takes a long time for PXE Boot during the downloading boot image file, you can change the registry settings to make it faster:

HKEY_LOCAL_MACHINE\Software\Microsoft\SMS\DP\RamDiskTFTPBlockSize

Type Reg_Dword
Value: 16384 Dec 
((Recommend that you increase this setting in multiples (4096, 8192, 16384, and so on) and that you not set a value higher than 16384.))
