Just adding my 2c worth here. I have seen this high activity in Resource Monitor and other tools, and am glad to have at last found that it is a real issue and not just a configuration problem of mine. Pleased to read that EN are addressing the issue. While I take the point made by @PinkElephant about the need to run from an SSD, as a matter of principle it is never good to have a task that is continually doing unnecessary IO. Certainly a product should not be designed to do that. To be generous, I assum it is a true "bug" or at least an "oversigt" in the design, and not a specific design feature. I look forward to a release with this issue resolved.
