Hard fault count drives performance
Just to emphasise how hard faults are determining for performance – here is a plot of hard faults versus page count for the same application mentioned in the previous post. The pattern is very similar, though it should be noted that increasing the page count does still keep the fault count coming down at the…

Which bit of a 4k page does your program use?
This follows on from the previous post – here are the plots. These are based on a run of the PARSEC benchmark suite x264 program – encoding 32 frames of video using 18 threads – 16 worker threads: the plots show how often each 16 byte “line” is used – whether as an instruction is…
