Thanks again for these figures. As you pointed out, I assumed the external interfaces would be the limiting factor and as the bridge is driven by the meta data it should perform fairly linearly. Another limit would be the complexity of the Action script manipulation which will vary depending on the circumstances. Is this correct?
It looks like the internal persistence module zips along very nicely compared with the external database versions. Are there any significant disadvantages with the internal version compared the the external database versions?
