I believe this is caused by the read algorithm of grub2. If the file
is continuous, grub legacy will read it in one pass, while grub2 will
break it up into small blocks, this will slow it down dramatically. I
haven't tested efi, but in bios mode, sometimes it takes twice as long
for grub2 to read the same file.
