Entity Framework Bulk Delete
BulkDelete allows you to improve EF performance by deleting multiple entities with bulk operations.
For HUGE performance gains, Entity Framework makes one database round-trip for each entity to delete.
So if you want to modify 10,000 entities, 10,000 database round trip will be required which is INSANELY slow. To use BulkDelete, you will need to use a third-party library.
|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|
