[tor-relays] Few questions about relaying

Hi and many thanks for developping this project !

I have a dedicated 200Mb (25 MB) fiber optics connection and a dedicated quad-core Linux server (64). What is the best setup to get maximum bandwidth usage ? I'm still stuck at 46.4Kb measured speed and 3,51MB advertised bandwidth. The server has direct connection to the Internet.

Should I run multiple relays on the same machine/IP ?

Thanks !
