Hi, I would like to ask about how the SQL connection pool works in FreeRADIUS. Does each thread use a separate connection from the pool, or can the same connection be used simultaneously by multiple threads? Can I basically say 1 Accounting/Access Request = 1 Thread = 1 Connection from pool?

The threads all share a connection pool. But it is impossible for multiple threads to share one connection at the same time. However, as soon as a thread is done using a connection, it is returned to the pool. Another thread can then pick it up from the pool and use it. Alan DeKok.
