2 weeks ago I just did some benchmarking and it looks like changing the above to initeng = 1 can reduce the number of allocations of aircraft of all classes, and speedups in all cases except for hydrogen (unclear why).
| Median t (ms) initeng = 0 | Median t (ms) initeng = 1 | Allocs initeng = 0 | Allocs initeng = 1 | |
|---|---|---|---|---|
| Default | 240.710 | 178.266 | 7109530 | 5155184 |
| Regional | 229.980 | 179.963 | 7126264 | 5187507 |
| Wide | 282.201 | 243.141 | 9132586 | 7022862 |
| Hydrogen | 1205 | 1253 | 29245689 | 26342920 |
Why does initeng = 0 in mission? This tells tfoper to start every Newton iteration from scratch. If it were 1, it would take the result of the previous sizing iteration as the starting point.
