Hi Anthony,


In the "why swap at all" thread, there was mention of the
/proc/sys/vm/swappiness tunable, and some people suggested echoing a zero
to there if you want to minimize/disable swap usage, or echoing a 100 to
maximize swap usage, etc.
But on my 2.6.5 system, I can echo a zero to there, then cat it back to
make sure... then 30 seconds later cat it again, and it's been changed to
something else (50, 60, 80something).
Is this supposed to be a value that can be manually adjusted, as some have
claimed, or is it something the kernel manages automatically? I definitely
can't manually set it without having it overwritten shortly thereafter.


I bet you have /proc/sys/vm/autoswappiness or the previous version of it w/o /proc stuff.

What option do I need to enable so I can get this control (to disable it)? I have sysctl enabled in 2.6.7-rc1 and no autoswappiness to be found.
