Coincidently, I had pretty much the same experience myself yesterday.  I ran a 
--bwlimit=512 across a (full) T1 line and my friend in the office next door 
complained because his real-audio stopped working.  I aborted it and tried 
--bwlimit=256 and network access was still slow, but his real audio feed 
was working again at least.

512 *should* be about half the line I believe.  I kinda wonder if there's a 
wrong multiplier somewhere.

    The Greatest tragedy in mankind's entire history may be the
      hijacking of morality by religion.  However valuable -- even
      necessary -- that may have been in enforcing good behavior on
      primitive peoples, their association is now counterproductive.
      Yet at the very moment when they should be decoupled,
      sanctimonious nitwits are calling for a return to morals based
      on superstition.
