I took care of that, caching structs metadata to limit useless repetitive introspections, and others simple stuffs. But of course if will always be slower than manually crafted code.

With Go the cost is ridiculous compared to round trips with database server and query execution. More productivity for just a bunch of CPU cycles. Of course each use case and constraints are different, they're is no universal rules.

Entity Framework... that is slow ! I don't know for EF Core, but EF6 is really a slow thing.
