Someone explain this strangeness with the progress bar (Iray)

fred9803

So I start rendering a scene and it gets to 7% after 10 minutes. I notice something I need to fix, G3F needs to to be a little bigger in size, I shut down the render, make her about 10% larger, and start to render again.

This time the render is sitting on 2% after 45 minutes. I didn't touch anything apart from that little resizing. The figure is only a very small part in the overall scene, about one 40th of the render dimensions.

The render appears to be progressing as quickly the previous one, but that little progress bar isn't behaving anything like it did before. And I've noticed this strange behaviour many times. What's happening?

Very wild guess, RAM choking? Sometimes it's a good idea to save the scene and close the program. Then open the program, load the scene and then render it.
