https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=187594 Steven Hartland <smh@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |smh@FreeBSD.org --- Comment #26 from Steven Hartland <smh@FreeBSD.org> --- I've actually been looking at this patch today in relation to my investigation of: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=191510 I would appreciate it if people could test the attached patch, which was created against stable/10 It should achieve the same as Karl's patch as well as: * More closely matching original Solaris logic * Provide better control of the reclaim trigger (absolute not percentage based, which becomes a problem in larger memory machines) * Uses direct kernel values instead of interfacing via sysctl's. * Should fix the issue identified in #191510 as well. Basic design is it will trigger ARC reclaim when free pages drops below vfs.zfs.arc_free_target, which by default is 3 x that of the VM's target free pages as exposed by vm.v_free_target (matching Solaris). -- You are receiving this mail because: You are the assignee for the bug.
