3500 authentications is what some setups have to handle in like 20 seconds :)
That said, databases are almost always the bottleneck when measuring capacity.
FreeRADIUS memory usage seem really negligible (at least when some dumb user does not add a memory leak... duh).
CPU usage can be quite intensive when handling heavy load. Still, that's not an issue, and it's laughably low compared to performance tests played on apache HTTP servers (for instance).

3500 users (over a day) is on the small side in terms of FreeRADIUS deployments. Your concurrent users are probably a quarter of that.

Try authenticating 2 Million subscribers after a major BNG outage. That 15% will make a big difference.
The Eduroam community, whilst one of the most visible users of FreeRADIUS, probably only represents about 10% of the users authenticated daily using FreeRADIUS, possibly even less.
