Entity Framework Extensions – Bulk Insert

Bulk Insert

Allow you to perform an INSERT operation.

var ctx = new EntitiesContext();
// Easy to use
// Easy to customize
context.BulkInsert(list, bulk => bulk.BatchSize = 100);

Performance Comparisons

Operations 1,000 Entities 2,000 Entities 5,000 Entities
SaveChanges 1,000 ms 2,000 ms 5,000 ms
BulkInsert 6 ms 10 ms 15 ms

SaveChanges 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 databases round trip will be required which are INSANELY slow.

Bulk Operations save entities in bulk to reduce the number of database round-trip required.
