Ok, N3050 cpu count was my mistake. It are 2 cores. It is a hand-size mini pc (ZOTAC 323 nano). It act as a middle node.
Now checked: The cpu load is ~15% with 1184 connected relays! (home connection with 10MBit/s; actual modem usage: 5MBit/s upload average, 8MBit/s peak. Downstream equal upstream.
(Sorry for wrong values before with an upload of 1MBit/s. I had forgotten my line upgrade some months ago.)
Relay fingerprint: E9A31E7EFF7A062AA67DA601CC70605AACF9F385 Relay external address: 91.48.47.161 Total traffic (read/written): 260.18 GB/263.10 GB Connected relays (1184)
ATLAS says 200 kByte/s (graph) >> ~2MBit/s Where is the mistake? I expect a lot more. The wrong value is stable over weeks.
One of my external VPS server:
Incoming / outgoing ~30MBit/s with a 100MBit/s connection
ATLAS says 4MByte/s (graph)
ARM display 40% cpu load with 5% for ARM itself.
RAM 4GB, 1 virtual core, XEON, ?? GHz
My confusion: ATLAS display MByte/s, not MBit/s. Every time I traped in this. It is a technical agreement, that serial lines are rated in Bit/s, not Bytes/s. It would be nice to change this in ATLAS.
I hope now my values are clearer than before.

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.
