Hello!

Definitions:

Page Reads/sec is the rate at which the disk was read to resolve hard page faults.
Pages Input/sec is the rate at which pages are read from disk to resolve hard page faults.

Q: Don't these two definitions have the same meaning?

Thank you in advance,
Michael

    Hello @Mikhail Firsov

    Page reads/sec indicates how many times the pages were read from disk, in a second;

    Pages input/sec is the number of pages read from disk.

    Hope this helps!

    Best Regards
    Karlie
