Hi,
I am compiling grubx64.efi with modulescpio exfat ext2 fat gzio

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.
I'm not sure if this can help, could you please test if swapping "case
0:" and "case 1:" at this position can reduce the problem?

It seems GRUB is likely to try freeing disk cache first before
requesting new pages. Although I'm not sure, but I think swapping
"case 0:" and "case 1:" may fix this problem.
Best Regards,

After swapping "case 0:" and "case 1:" works fine.
