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.
