            Bug ID: 208373
           Summary: gstat: strange I/O statistics
           Product: Base System
           Version: 10.2-STABLE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: freebsd-bugs at FreeBSD.org
          Reporter: la5lbtyi at aon.at

Scenario:
- Writing data to a SEAGATE ST32155N
- Controller is Adaptec AHA-2940AU
- Running "gstat -f da0"

Result:
- gstat shows the following output:

 L(q)  ops/s    r/s   kBps   ms/r    w/s   kBps   ms/w   %busy Name
  285     57      0      0    0.0     57   3641   2017   99.6| da0

Expected result:
- The product of w/s and ms/w should be less than 1000.
- Or the manual page should explain what the numbers mean.
