so what gives. different man pages show different things for IO bi and bo ???
shouldn't bo mean "blocks out" and bi "blocks in" from perspective of the cpu ??
does redhat compile their vmstat differently ??
http://unixhelp.ed.ac.uk/CGI/man-cgi?vmstat
IO
bi: Blocks sent to a block device (blocks/s).
bo: Blocks received from a block device (blocks/s).

IO
bi: Blocks received from a block device (blocks/s).
bo: Blocks sent to a block device (blocks/s).
[my system]
Red Hat Linux release 9 (Shrike) [
and yeah, i know, very old OS]
vmstat -V procps version 2.0.11
man -V man, version 1.5k
man vmstat says:
VMSTAT(8)
IO
bi: Blocks sent to a block device (blocks/s).
bo: Blocks received from a block device (blocks/s).
