Entity Framework Bulk Update Library

Introduction

Entity Framework Bulk Update library allow you to improve EF performance by updating multiples entities with bulk operations.

Why using Bulk Update with Entity Framework?

For HUGE performance gains.

Entity Framework makes one database round-trip for each entity to update.

So if you want to modify 10,000 entities, 10,000 database round trip will be required which is INSANELY slow.

Operations 1,000 Entities 2,000 Entities 5,000 Entities
BulkUpdate 50 ms 55 ms 65 ms
SaveChanges 1,000 ms 2,000 ms 5,000 ms
