MEMORY report
PAGE TRANSFERS
READ
Number of 4-Kb pages read per second
WRITE
Number of 4-Kb pages written per second
Note
The sum of read and written pages does not match the IO’S PER SEC PAGE value of
the ACTIVITY report. Memory management tries to group up to eight 4-Kb page-out
pages (WRITE) for one input/output operation (SDV or START-SUCHANNEL). Each
READ causes one 4-Kb page to be transferred, i.e. causes one input/output operation
(SDV or START-SUBCHANNEL) (see also section “page fault” on page 451 of the
glossary).
