There are times where PXE booting seems to take a long time especially with WinPE. After making some changes to the MTU (Maximum Transmission Unit) I was able to download WinPE 1.6 and 2.1 under 20 seconds.
Note: this depends in the speed of the network; all my tests are in a fast network.
Launch PXE Configuration tool and select the Multicast tab.
Change the Packet Size from 768 to 1456. Now this works OK for me and I have seen reports that others had success with this as well. If this does not work revert back to 768.
Finally, click save then wait for the progress bar to disappear. Click OK to close the PXE configuration tool. PXE boot a client the PXE download should be a lot faster.

Multicast affect the Booting time
I thought that justt affected the update time. So there was a multicast TFTP update to your different PXE servers, not a multicast distribution of PXE.

RE:Multicast affect the Booting time
The update time from PXE manager and PXE server? no, these are the packets sent to the client when PXE booting.
Again DOS PXE is the only one that does multicast.
