TFTP Block Size

[MikhailCompo]

So I am total novice when it comes to iPXE having only discovered it recently, however I have noticed that the boot performance is not great, from a gen 2 Hyper-V guest (gen 2 being UEFI).

The performance out of the box is similarly poor, when using SCCM + WDS to PXE boot a gen 2 Hyper-V guest, but was dramatically improved when changing the RamDiskTFTPBlockSize and RamDiskTFTPWindowSize.



I have no idea if these settings apply to iPXE efi or not, can anyone enlighten me? Or do they relate to the TFTP server (Tiny PXE Server in my case)?
