[tor-relays] 1gbp/s Tor Relay

Hello, I was wondering if it's possible to allocate 1 Gbps of bandwidth to my Tor relay, or if it would be better to create multiple instances on the same server?  I have a dedicated server in a data center. When I look at the list of the fastest relays, I see that some manage to reach 1 Gbps on a single instance, but I assume that requires a very powerful CPU and a very high single-core clock speed, given that my CPU is a bit old. Thanks!
