[tor-relays] One IPv4 address, 1Gbit connection

Hi,

I'm running a Tor exit node on a 1gbit connection. Currently it's maxing at about 180Mbit/s (both ways, so 360Mbit/s) per instance, and I'm running two instances.

That's not really using the connection well. The box has 4 cores (no AES-NI) and I'm looking for ways to utilize the other 640Mbit/s.

Sadly it's not possible to get more IPv4 addresses on this box. I do however have access to a big range of IPv6 addresses.

Can I somehow run more Tor instances on this box by utilizing those IPv6 addresses? Or are there other ways to optimize the throughput and get closer to that 1Gbit?

Tom
