Hello everybody,

what a pitty
so we can’t use ipxe if we have uefi with secure boot on.
All Systems that are shipped with Windows 8 have this
option enabled and I don’t have the authority to disable this
function.

ipxe works in uefi mode really quick and fast.

When i boot winpe over tftp in legacy mode without ipxe it
takes 20 seconds to boot. When i boot winpe with bootx64.efi in uefi mode over tftp without ipxe it takes 4,5 minutes.
Secure boot on worked here, but it's to slow.
Does anybody know why the performance is so slow. The transfer rate
from our server is 1,1 MB/s.

It doesn't matter which hardware we use. It's always slow
