SDK 1.1.5 released - App Engine development speeding up?
Among the new features, the one that really caught my eye was: "Sped up the datastore stub."
I didn't notice a speed up in the initial start-up time of the dev server with a large datastore, but it does seem that my app is more responsive. I need to test further and get some real data though.
One thing I've noticed is that the mean time between SDK releases has been decreasing quite considerably as of late. I hope that means that development on App Engine is speeding up and that we'll start seeing new feature implementations on the deployment environment also.
