No. It may make some authentications work faster, but the server itself won't run faster.
With this option if a client has been authenticated earlier the freeradius won´t do the files / sql / ldap authorization?
It will still do some of that, depending on your configuration.
Is there any risk if the server receives a heavy amount of authentication requests?
