I do not have any experience with EF but bulk operation performance appears to be a common problem with EF. Common suggestions are to use

yourContext.Configuration.AutoDetectChangesEnabled = false; yourContext.Configuration.ValidateOnSaveEnabled = false;

Perform SaveChanges() on sets of rows - set size vary depending on the poster so you may want to experiment.

Rebuild the context after n number of inserts. Again, n varies depending on the poster - like SaveChanges, experiment.
