Oh here's a specific question: Pagefiles. Sorry to double-post this one but I didn't want this question to be lost.
My previous practice, was to set the swapfile to the minimum size allowed, for both the minimum and maximum pagefile size, thus ensuring that the file was rarely used and never shrank+grew and created fragmentation. I have 16GB of fast RAM and it shouldn't need a pagefile, I'd guess.
Now, I'm on SSD. Should I disable the pagefile entirely?
Same question for hibernation files? I won't be needing any sleep function at all.
