Slow loading and GRUB work after commit 938c3760b

[jim945]

Hi,

I am compiling grubx64.efi with modules cpio exfat ext2 fat gzio iso9660 loopback lzopio newc normal ntfs part_gpt part_msdos probe read search tar test configfile echo xzio squash4 sfs memdisk

The prefix is stored in the sfs container.

After applying patch 938c3760b, the boot time before the menu appears reaches 15-20 minutes. The work is very slow.

 And in Qemu this problem does not appear.
