Bandwidth-Delay Product
System administrators who wish to get maximum network performance across long, fast network connections may want to tune the TCP networking parameters on their systems. To know how to tune those parameters we need to compute something called the Bandwidth-Delay Product, or BDP. Much to the chagrin of network engineers, us simple sysadmins can often think about simple (non-LACP) server network connections like water pipes (or sewer pipes if we are feisty). Larger-diameter pipes can move more liquid at once, similar to a network connection that has higher bandwidth. Longer pipes require more time to reach the other end, which correlates to latency. And while you might not think about …
