+Java 25.0.3+9-LTS-195, one JVM, 200000 iterations per round, best of 5 rounds after a 50000-iteration warm-up
+mapping: Customer -> CustomerView (1 address, 1 order with 2 lines, 1 set, 1 map)

+hand-written             95 ns/op
+MapStruct 1.6.3          92 ns/op   (1.0x hand-written)
+Dozer 7.0.0           11498 ns/op   (122x hand-written)
+
+first call, cold: MapStruct 0.13 ms, Dozer 80.9 ms
