This sounds wrong. VIA Nano 1.6GHz, a single core laptop CPU from 2011, can sustain about 40+40 Mbit (WITHOUT utilizing the crypto acceleration).
The Celeron N3050 has two cores and supports AES-NI, and if OpenBSD seriously doesn't (which I doubt), then swap out OpenBSD.
With two cores you could also run 2 instances of Tor for more efficient CPU use. I would expect both cores stay at sub-50% CPU use while the entire thing is capping out into the full 100+100 Mbit.
That said, when did you measure the speed, and are you aware of https://blog.torproject.org/blog/lifecycle-of-a-new-relay ?
Another possibility, maybe your ISP only provides "up to 100 Mbit" and is shaping certain types, patterns or amounts of traffic use.
