With the increasing implementations of gigabit networks and the increases in network bandwidth over wide area networks (WANs), network throughput is not as much of a bottleneck as it used to be. That’s not to say network performance issues do not arise. For example, a bad or misconfigured router can cause all sorts of network performance issues, especially if your users and your SQL Server are on different sides of the ...
