Since BFS was mentionned and never installed, I did some mods. I copied the fah folder files to a new folder, except TheKraken, the work folder, the queue.dat file and the A5 Core. I installed BFS (the scheduler) and started folding with that new fah folder. Obviously, a 6901 was initially downloaded... just like my 4p is folding ATM.
Output? Exactly twice the tpf. 10:01 for the 4p, and 20:07 for the 6272... so Interlagos is a failure when it comes down to tpf performance. It wins in the heat and power consumption deptartment though.
Now, do I order a second 6272?
