Subject2.6.17-mm6 vmstat breakage
FromMike Galbraith <>
DateThu, 06 Jul 2006 09:38:43 +0200
Greetings,

My single P4/HT box is showing incorrect pgpgin pgpgout numbers with
this kernel.  While disk throughput for dd if=/dev/hdc of=/dev=null
bs=4096 count=1000000 produces about 57MB/S (up ~14% over 2.6.17 btw),
vmstat (procps version 3.2.5) is only showing about 7MB/S.
Looking at the numbers in /proc/vmstat, it looks kinda like pgpgin might
be pages instead of the KB it used to be, with some added >>=1 action on
the side.  At any rate, the numbers below are horse-pookey ;-)
