  The main way to make DBs faster is to (a) not use the DB, or (b) batch up insertions, or (c) shard the data across multiple DBs.

  Yes.

	if (Framed-IP-Address < 10/8) {
		sql1
	}
	elsif (Framed-IP-Address < 171/8) {
		sql2
	}

  Yes.  At the top of the "accounting" section, do:

	if (Acct-Session-Time == 0) {
		ok
		return
	}

  Though if you're running 3.0.16, that message doesn't appear in the source or in the logs.

  Are you sure that you don't gave two copies of FreeRADIUS installed?  i.e. one which is v2, and another v3?
