I don’t think that’s completely true - you have mysql passwords, etc. configured, I presume.

You have not answered my questions.

What is your usage profile like - what sort of throughput do you see for different packet types?

Can you share some debugs of auth and accounting messages?

Have you looked at the MySQL logs and slow query logs and so on? Run any MySQL tools to analyse performance? This is, after all, a MySQL performance issue, NOT a FreeRADIUS performance issue.
