1.5M block import time (VerifyBlocks disabled) on AMD Ryzen 5 1600/16GB/HDD, before: real 159m16.551s user 69m58.279s sys 7m34.334s after: real 139m41.836s user 67m12.477s sys 6m19.420s 12% which is even a bit more than could be expected from inputs analysis (that has around 10% cache hits for a block-wide cache), worth doing.
