Minimum of ARC is set to 1/8 of all memory or 64MB (whichever is more). Could you locate these lines in sys/contrib/opensolaris/uts/common/fs/zfs/arc.c file: /* set min cache to 1/32 of all memory, or 64MB, whichever is more */ arc_c_min = MAX(arc_c / 4, 64<<20); Change 64 to eg. 32, recompile and retest? -- Pawel Jakub Dawidek http://www.wheel.pl pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
