I have ported the dynamical core of our C++ CFD code to Julia a while ago, and see now huge speedups going from 1.8 to 1.9 (170 sec to 21 sec to first model step). Inspired by many discussions on this forum, I tried to precompile all functions triggered towards the first model step, but I do not see…

Precompilation of complex code does not make time to first model step faster
