bjorn3 (Dec 02 2024 at 13:13):There shouldn't be any initialization for Module. If you are clearing and reusing the Function/Context between multiple defines rather than creating a new one from scratch, it is possible however that the difference is caused by memory allocations cached in the Function/Context.

Makes sense! Are there any benches out there on compile speed?
