- route1: ops class is value class + by-name 2nd arg
- route2: ops class is value class
- route3: by-name 2nd arg
- route4: standard operator (
~)
The test classes use routing trees with different depths and branching factors. All benchmark methods evaluate the same 1000 requests.
- Main_10_10: depth 10, branching factor 10
- Main_10_3: depth 10, branching factor 3
- Main_3_10: depth 3, branching factor 10
- Main_3_3: depth 3, branching factor 3
Summary of measurements: The concatenation combinator that is implemented by a value class and whose 2nd argument is by-name (i.e. route1) has the highest throughput and the smallest normalized allocation rate for all considered structures of routing trees. The difference in performance between the various concatenation operators gets more pronounced for deeper and broader routing trees.
