I don't see any high CPU usage here. The ARC cache grows based on current I/O activity (and can grow quite large) but can be tuned down (at least in Solaris) if necessary. As far as the memory consumed by ZFS vs UFS it is pretty difficult to tell since UFS can be quite aggressive at caching as well. The UFS caching is often hidden by system tools and reported as unused memory. ZFS definitely prefers a 64-bit kernel.
