Thanks Tame. That is some cool results with running in Linux Shell.

anyone testing the AMD RX580? Just curios...Now that AMD OpenCL is on par and even better than CUDA with full support for all the Blender features, I even think of buying 2x RXVega, when it will be out (AMD have already confirmed that they will be releasing Vega graphics cards in the first half of 2017)...so, I hope that I can get something like 15s (2xVega) for 500,-Euro, that would be 3x better than 2x gtx1060...we will see... Anyway, I see OpenCL much better than the bottle-necked Cuda also because is not proprietary and it is developed by a huge amount of people...It is like Apple vs Windows-PC, Windows PC is much, much better, more flexible and cheaper...

Weirdness - or user error - but having migrated back to Linux, I get crappy GPU results and something is wrong because set at 480x270 (as I always have for GPU tests) Cycles renders all four tiles at once with a time around 2 minutes... I had <30 secs in Windows with my two GTX1070 and it rendered 2 tiles, then one, then the last...
^ forget about that. I won't even admit how immensely stupid I was, but be assured it was on an epic level. Epic!
