It's how RADIUS works. If you want to know more, read RFC 2865 and RFC 5080.

<shrug> If the server is blocking in rlm_rediswho, then the database does have issues.
Maybe you're using another database too, and that database is also slow.
Again, this isn't complex FreeRADIUS can do 50K packets/s if it's just doing ACKs. If your system isn't doing that, it's because of local changes.
We've run FR with sustained loads of 5-10K packets/s to a database. But that is a very carefully designed system.
