Hi pe, appreciate your contributions and sad but understand the decision to leave.

The performance issue you're describing is most likely this one, unfortunately caused by a bug in Virtualbox which is completely out of our control. As mentioned in the link, a partial workaround is to limit the number of cores used by the camb_boinc2docker app. If you leave at least one core completely idle, or even in use but crunching non-vbox apps, that should still keep your computer responsive.

Anyway, we will certainly post once that problem is solved on the VBox end.
