Sorry about my fault about the experiments, here is the real one.
Btw, apparently, there are still some questions about the results and I will sync with Kirill about his test command line.
Below is just some simple experiment numbers from this patch, let me know if you would like more:
Tested on Xeon machine with 64GiB of RAM, using the current default fault order 4.
Sequential access 8GiB file Baseline with-patch 1 thread minor fault 8,389,052 4,456,530 time, seconds 9.55 8.31
Random access 8GiB file Baseline with-patch 1 thread minor fault 8,389,315 6,423,386 time, seconds 11.68 10.51
Best wishes, -- Ning Qu
