Entity Framework Bulk Delete Library

Introduction

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

Why using Bulk Delete with Entity Framework?

For HUGE performance gains.

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

So if you want to remove 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
BulkDelete 45 ms 50 ms 60 ms
SaveChanges 1,000 ms 2,000 ms 5,000 ms
