The best way to speed up restores is to not use mysqldump at all.
Instead take a snapshot of the filesystem with something like
mylvmbackup. Then restore is as fast as copying the files over.


Also mysqldump adds disable keys and disable unique checks to the
output by default when using the --opt flag.
