I think 300KB/s is around the max possible in the current implementation:

Encryption, latency, and how a tunnel is built makes it quite expensive in CPU time to build a tunnel. This is why a destination is only allowed to have a maximum of 6 IN and 6 OUT tunnels to transport data. With a max of 50 kb/sec per tunnel, a destination could use roughly 300 kb/sec traffic combined ( in reality it could be more if shorter tunnels are used with low or no anonymity available). Used tunnels are discarded every 10 minutes and new ones are built. This change of tunnels, and sometimes clients that shutdown or lose their connection to the network will sometimes break tunnels and connections. An example of this can be seen on the IRC2P Network in loss of connection (ping timeout) or on when using eepget.
