I had them at numbers varying from 0 to 3 though, most of them at 1, and still.... switching it off entirely made it faster the ones in Branched Path Tracing, I mean. The general Pixel Samples I just crank it up to 600, tick on Progressive Refinement and let it cook in the background until I'm satisfied and stop the render.

I was also having the problem of going to bed with a render cooking, then returning to find that my computer had simply rebooted itself sometime during the night. I think we have some short power outages on occasion at night time here, or it was rebooting from the heat (it's summer in Brazil and we're having a baaaad one). And yeah I wasn't enjoying leaving the computer on with this heat anyway.
