[tor-relays] Tor Network Map advertising available B/W way too low

Hello, I just set up an exit node (PrivacyFoundation on the list), and while I've got 5mbps up, it only advertises as 80-90kb b/w available. That's not at all accurate, and I think it's meaning the connection is ending up way underutilized, since I'm not seeing much traffic on the b/w graph. How do I change the advertised b/w? Thanks!
