Simulating Network Latency

John Paul Cook shows how to use WANem to simulate network latency in a Hyper-V environment:

Access WANem from either SQL Server virtual machine using a case sensitive URL that includes WANem’s IP address. In this example, the URL is http://99.99.99.99/WANem. Inside the SQL Server virtual machines, I set the browser’s start page to the WANem home page. Create a delay of 1000 msec and retest SQL Server to SQL Server connectivity.

It looks like a good way of proving out whether your setup can handle extreme latency before you build it for real.

One of the top written to tables was, based on our naming convention, a […]
