Thanks for your reply.

Yes, the only difference is that cpanel server has ext4 over LVM over mdadm RAID 1, and the non-cpanel (faster) has no LVM, it's ext4 over mdadm RAID 1 partitions directly.

As for the engines, the tables are mixed MyISAM, InnoDB, but the one being altered is InnoDB. Same set of queries used to create and alter tables, so yeah.
