In the link http://blog.fpmurphy.com/2010/03/grub2-efi-support.html , the author F P Murphy mentions that disk cache size assumed for grub2 uefi leads to longer boot times when compared to grub2 bios. According to him, in (grub2-source-dir)/include/grub/disk.h
lines /* The size of a disk cache in sector units. */ #define GRUB_DISK_CACHE_SIZE 8 #define GRUB_DISK_CACHE_BITS 3 should be changed to /* The size of a disk cache in sector units. */ #ifdef GRUB_MACHINE_EFI #define GRUB_DISK_CACHE_SIZE 8192 #define GRUB_DISK_CACHE_BITS 13 #else #define GRUB_DISK_CACHE_SIZE 8 #define GRUB_DISK_CACHE_BITS 3 #endif for faster boot. Is this change needed? I have about 4-5 sec gap between "Welcome to GRUB" and the GRUB2 boot menu in UEFI x86_64. _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
