BulkSaveChanges

Introduction

BulkSaveChanges allows you to improve EF performance by saving multiple entities with bulk operations.

Why BulkSaveChanges?

For HUGE performance gains, Entity Framework makes one database round-trip for each entity to insert/update/delete.

So if you want to save (add, modify or remove) 10,000 entities, 10,000 database round trip will be required which is INSANELY slow. To use BulkSaveChanges, you will need to use a third-party library.
