Short answer: yes — adding more relays is a reasonable experiment if the host 
has spare CPU, RAM, and bandwidth. Add ~2–4 relays and allow 2–12 weeks for 
traffic and bandwidth authority measurements to ramp up and stabilize; there is 
no automatic increase beyond that.

Running many relays per IP (e.g., 16) can help only until host or network 
limits are reached; beyond that, it adds complexity without increasing 
aggregate throughput.

Adding relays will not help once CPU cores or RAM are saturated.

Generalization:

Guards: ~1 relay per CPU thread, ~3–6 GB RAM per relay
Exits: ~1 relay per CPU thread, ~2–3 GB RAM per relay

The cost imbalance you’re seeing is expected today: operating relays outside 
the EU materially improves network diversity, but it can be significantly more 
expensive per unit of traffic than running relays in EU-dense locations.
