[tor-relays] Home broadband - worth running a relay?

Thanks for the advice Thomas.

What's the exact meaning of RelayBandwidthRate in torrc? I ask 
because I found having more than about 20Kib/s upload limit for 
bittorrent made my connection largely unusable, but leaving it 
without a download limit was fine (damn asynchronicity). How should 
I decide what an appropriate value should be? Twice the maximum 
upload limit I can devote to it? Or if I left the value unset would 
tor likely do a good enough job of deciding on an appropriate 
bandwidth value?
