Is rEFInd faster than GRUB?

rEFInd’s scans for kernels and boot loaders can take a couple of seconds on each boot, so it may be a bit slower than GRUB to appear. (You can minimize this scanning time by installing only those filesystem drivers you actually need and by keeping the partitions that are scanned uncluttered.)

Where are the configuration scripts in GRUB 2?

Configuration changes are normally made to the /etc/default/grub file and to the custom scripts located in /etc/grub.d. No changes are made to the GRUB 2 menu until the update-grub command is run as root. This command runs the GRUB 2 configuration scripts and updates the /boot/grub/grub.cfg file.
