if the files won't change, and they really are opaque blobs, definitely prefer blobstore. it shortcuts much of the app engine serving stack, so it will usually be somewhat faster and more reliable than the datastore. probably only by a small constant factor, but that's still something. > Great.

(that's average, of course. spikes will always happen occasionally. still, we've managed to reduce them pretty significantly in the last few months too.) -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
