SubjectRe: [PATCH 0/1] mm, shmem: map few pages around fault address if they are in page cache
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,
