Thanks for the interesting information.
The low performance for multi-precision operations is not surprising.
While this version of Mathematica can probably be improved a lot, it cannot not reach parity with x86, because this (support for multi-precision operations) is exactly the area were the ARMv8 ISA is the most deficient compared with the x86 ISA (especially since Broadwell, but also Intel since Nehalem & the AMD before Bulldozer were far above any competition).
Other deficiencies of the initial ARMv8 have already been addressed in the later extensions (e.g. atomic operations), but I have not heard anything about any plans for bignums.
