I will no doubt be selecting a 64-bit capable CPU. My main concern is whether getting a dual core vs single core processor will give ZFS any noticable performance gain. Is ZFS multi-threaded in any way? I will also be heavily using NFS and possibly Samba, but a single core processor with a much higher clock speed is much cheaper than the dual core offerings from AMD. Also, there is a premium price for extra L2 cache. Would the ZFS checksum'ing and parity calculations benefit at all from a larger L2 cache, say 1MB? Or would the instructions fit fine inside 512kB? I know it depends on the application, but some general info on this subject will help my selection.
