[syslinux] syslinux EFI64 6.03 Slow Loading

[David F.]

Hi,

I'm wondering if it's the EFI syslinux 6.03 version that has slow
transfers dealing with the TFTP server?   I got everything working
using 6.03, but man, it was slow loading initrmfs.gz.  Took almost 10
minutes!  I see something about speed improvements in 6.04, is that
what that helps?  If so, Where are the binaries for it since I can't
build pre-1 version due to missing items in gnu-efi.

TIA!!
