Is the InnoDB on Percona Server really XtraDB, so if I switch my XF board to Percona, I will get XtraDB without any extra work? Or will I have to manually migrate the InnoDB tables to XtraDB? I have a VPS with 1G RAM, currently running Oracle's MySQL 5.5. Is switching to Percona a good idea? I don't mind the work involved at all, but unsure of the benefits.
