I have been experimenting with lowering the I/O priority during restraint, an option that has been available since v5. I've not seen any troubles, but I like more real world testing before making such a change. Has anyone made use of this feature yet? Any issues you've seen with your applications? Everything should be fine, but as I've learned there is always some freak application or scenario that only my users can tell me about ;). Thanks.
