Message-ID: <CACQD4-5U3P+QiuNKzt5+VdDDi0ocphR+Jh81eHqG6_+KeaHyRw@mail.gmail.com> (raw)

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,
