Hi, there's reject_delay in radiusd.conf
It is typcially set to one second to prevent some attacks. You could set it to zero and then the reject may come through faster. Still, 300 ms is *really* low even for that - depending on the time your auth backend needs to even determine whether it was success or failure may take longer than that.
