  Your "somebody" was right in suggesting that you disable trailers  (tho I
  doubt that you will see very much difference in network performance: your
  cpus outrun your ethernet cards by a wide margin).  See mail on this issue
  two weeks ago: the trailers option is not all that standard anymore.

  Regarding the man page:  its one of those man pages that should have been
  revised years ago, since (in this case) it was written when systems were
  much, much slower - in all respects.
