https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=238200 Bug ID: 238200 Summary: top(1)'s Swap In and Out numbers are twice as much Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: ota@j.email.ne.jp top has been reporting twice as high as actual transaction for swap-in and swap-out. Swap: 2048M Total, 201M Used, 1847M Free, 9% Inuse, 27M Out In this line, top reported 27M Out. However, systat -vm only shows 13.5 MB transaction for the same period to the device. We need 3 terminals to observe: term1 % top term2 % systatm -vm 1 term3 % swapon <large-device> term3 % mount -t tmpfs tmpfs /mnt/tmp term3 % dd if=/dev/zero of=/mnt/tmp/large.txt bs=1M count=3000 Also Having 1 swap device makes easier to observe. -- You are receiving this mail because: You are the assignee for the bug.help
