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

[Ning Qu]

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
