I'm having the same issue when i try to findAll with include all and nested true options it greatly increase the amount of time that it takes to give a result (i have about 10+ relations (oneToOne) in a table and the more i add them to sequelize the slower it takes). I've done some testing removing sequelize-typescript dependency and the speed just comes back to normal. Is there any way to fix this?

sequelize-typescript doesn't really modify this, if it's the library issue, it's probably down to sequelize, so might be better to check there for support.

Though, would be helpful to share your code snippets and DB setup as it might be down to it.

Yeah, yesterday i was testing again the code (with sequelize-typescript) and it was very fast again to fetch data. So we discarded the idea it was sequelize-typescript. It is kinda crazy some times it takes 8s and in another day takes 200ms, i really wonder whats going on to this to happen.

@namett3 please try include models with separate: true flag. Maybe it helps you.
