General Usage

We see that the initialization of an MTK problem, using Julia 1.11 is much faster than with Julia 1.10. For details, see: System initialization on Julia 1.10 is slow · Issue #233 · ufechner7/KiteModels.jl · GitHub

Julia 1.10:

[ Info: System initialized at:
Time elapsed: 26.04489362 s

Julia 1.11:

[ Info: System initialized at:
Time elapsed: 6.724497246 s

Is this to be expected, or do we have bug in the way we precompile?

If you want to reproduce our results, follow the instructions at GitHub - ufechner7/KiteModels.jl: Kite and tether models for the simulation of kite power systems

and then run:

include("examples/ram_air_kite.jl")
