Comment 9 for bug 944347

Adam, there's a bug in your version of the patch "efi_disk_cache.patch":

  +#define GRUB_DISK_CACHE_SIZE 1024
  +#define GRUB_DISK_CACHE_BITS 8 <---- SHOULD BE "10"

You may have been misled by Manoj's suggestion of trying BITS==8... But note that 2^BITS must be kept == SIZE which isn't the case in your version of the patch.

Anyway, I have determined that BITS==10, SIZE==1024 is a good value performance-wise (and the blog poster suggests even higher: BITS==13). I recommend that we stick with BITS==10, SIZE==1024.
