Using 2 x 8-disk raid6 connected by raid0 (or linear concat for XFS) will be faster and safer than a single large raid5/6 array, but unless you use the latest multithreaded raid kernel then it will still be very slow.
Not as far as I understand it, it won't. The multithreaded code is only really a benefit on SSDs which can manage tens of thousands of IOPS, while on spinning rust HDDs which can only manage hundreds of IOPS, the single-threaded code is fine.
