Entity Framework - Bulk Insert
Introduction
BulkInsert allows you to improve EF performance by inserting multiple entities with bulk operations.
Why BulkInsert?
For HUGE performance gains, Entity Framework makes one database round-trip for each entity to insert.
So if you want to add 10,000 entities, 10,000 database round trip will be required which is INSANELY slow. To use BulkInsert, you will need to use a third-party library.
| Operations | 1,000 Entities | 2,000 Entities | 5,000 Entities |
|---|---|---|---|
| BulkInsert | 6 ms | 10 ms | 15 ms |
| SaveChanges | 1,000 ms | 2,000 ms | 5,000 ms |
