Not true.  If you turn on MS TCP or solaris TCP or whatever you
won't get line rate out of the box awithout tweaking things a bit,
but you can make *TCP* do it.  Some folks here have pushed TCP to
over 500 Mbps over an OC-12 satellite channel with the normal,
everyday TCP implementation in solaris.  (I.e., when you discount
header overhead, etc. they got very close to line rate).
