  The complaints about performance problems are largely things like:

- overloaded SQL databases
  - no indexes,
  - long-running administrative queries blocking FreeRADIUS

- system overload
  - a small system being asked to authenticate 100K users in 10s
  - many PEAP authentications per second on a small system

  I've done tests with 1M accounts in the "users" file.  The server
takes 3 seconds to start, and then does 50K+ authentications per second.
 Which is about the same speed as when there's 10 accounts in the
"users" file.

  There are no performance problems inside of FreeRADIUS.
