Right now my ARC is 17GB, and in some situations it seems slower with the excess caching. Here are the memory settings I used. vm.kmem_size="512M" vm.kmem_size_max="1024M" vfs.zfs.arc_max="512M" One major difference is I'm using amd64, not i386. Although ZFS works on i386, it uses a lot of 64 bit math, for performance reasons you should use ZFS on amd64.
