I am running FreeBSD-7 with the following: m.kmem_size="512M" vm.kmem_size_max="512M" vfs.zfs.arc_max="256M" vfs.zfs.arc_min="32M" vfs.zfs.prefetch_disable="1" on a i386 machine with 1 Gig memory (now upgraded to 1.5 Gig) and i have not experienced, up to now, any lockup problem. Apparently the kernel effectively uses around 500M memory, indeed. Performance seems reasonable to me, not worse than with UFS. -- Michel TALON _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
