Entities are fetched whole, so if you have a large Blob property and you are fetching it all the time, it would take longer than fetching an entity without a Blob property. Unless you're frequently (every request) retrieving a large Blob, this shouldn't be *that* expensive. Small blobs shouldn't take that much longer. Your mileage may vary, so you'll have to do some benchmarking to see.
