Batch Image Insert

System

Using 4.5.3 of the MediaBin Web Service SDK with Java, I've been trying to put together a script to batch insert a large number of images into MediaBin.

I'm currently calling the InsertAsset method for each image, which appears to be a rather slow method to insert the images. Even switching to using the InsertAsset_IndexExternal method didn't over much in the way of additional speed (it still takes about 3 seconds per image.)

Is there a faster way to do this?
