My most populated UBNT has 43 people on it (too much), RTS 768 on each client radio, the CPU utilization averages 32%, peak of 68%, no complaints of performance. Our AP's do very little however no routing/no nat/no auth, traffic shaping/auth is done at the IP level on the redback. I plan to swap the radios out at this tower for BulletM series radios in non-airmax mode as they have 3 times the CPU horsepower, and I should be able to get close to 100 per sector on my legacy towers I believe.
