Nope, I had sync disabled across the board.  There are people on the nexenta
boards who are ticked because nextentastor only allows zvol iscsi targets
(via the gui...)

there are two factors that you may want to look at:

 1) block size.  files default to a 128K allocation block size, while
zvols default to 8K.

 2) check the "sync" property; the zvol may be generating synchronous
writes while I/O to the file isn't.
