5.1 isn't tuned yet to deliver high performance, so it isn't a surprise
to see a lower performance than 4.x. But 50% is much... are you sure you
did the test under the same conditions (e.g. are you sure the write
cache was off (or on) in both cases, no debugging switches activated in
the kernel/userland)?
