EF Code First: is good to call DetectChanges just before SaveChanges?

Question

I have read few articles (article1, article2) about Entity Framework that it calls DetectChanges many times, which makes it very slow when working with large amounts of data

Answer 1

One of the main problems that can be resolved by DetectChanges is persisting data in EF when we have ManyToMany relation and AutoDetectChanges=false.
