In my tests, the exported How are you performing your testing? Do you have a zfs server directory and are copying files from the server to a client? What size are the test files on your server? How much RAM does your server have and how much is zfs allowed to use? What program are you using to perform the copy? Is the copy sequential or can it be done in parallel via multiple processes/threads on the client? Are you only interested in single threaded read performance to a single client?
