With my example for login, my assumption was that one would use short-lived TCP connections (i.e. server receives login packet, sends success&#x2F;fail and finally closes the connection), not a simultaneous, persistent connection where TCP congestion (and thus UDP packet loss) becomes an issue. But maybe I&#x27;m wrong on this one.<p>Thanks for sharing by the way, great article (although as an aside, some of those graphs are really hard to read).
