https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D229670 --- Comment #4 from Shane <FreeBSD@ShaneWare.Biz> --- (In reply to vermaden from comment #3) The patch in review is about ARC releasing its cache when programs want more memory, not about using more than the limit. Currently the system can swap out before it releases ARC, the patch changes that, so that when free ram is used, it will release ARC before swapping. T= his means it may not always be using the arc_max that it is allowed to use. Also, in the Oracle ZFS docs, it states that arc_min/arc_max have a range of 64M to physical mem. I wonder if there is a minimum amount that a zpool nee= ds based on number of disks, blocks in pool, number of files... Maybe this is preventing the smaller memory use. --=20 You are receiving this mail because: You are the assignee for the bug.=
