Notes on data collection: in all cases times represent the time to complete the item import call from first byte sent to last response byte received. (For users on a slow network, the upload time may be nontrivial as well.) For the faster tests results were averaged across several runs but were generally consistent. Median times were quite close to average times. Image sets were the same between runs and come from the HST image collection. Larger images take longer, though not linearly so.
