It seems that the performance bottleneck is the array controller hardware (particularly for writes), followed by the connection between the host and the array. ZFS does increase the amount of I/O traffic from the host to the array (double for mirroring) but there seems to be minimal performance impact from that as long as the load is reasonably balanced.
