Sorry if I've missed this, but what tuning have you done for ZFS? Some
of us (most of us?) have seen fairly "sluggish" performance when
prefetch is enabled (the default), while the system is generally more
responsive when prefetch is disabled.
This may have nothing to do with the problem you've stated, but I
thought I'd throw it out there.
