Account for the Bandwidth-Delay Product with Larger Network Buffers
This is post #14 in my December 2013 series about Linux Virtual Machine Performance Tuning. For more, please see the tag “Linux VM Performance Tuning.” At times we can refer to certain network concepts with a “pipe” analogy, where bandwidth is the diameter of the pipe and latency is the length of the pipe. A garden hose has a certain limited amount of “bandwidth” because it has a small interior diameter, and has a lot of latency because it is so long. Water you put in one end of the hose takes a while to come out the other end. A house in the USA likely has a main sewer pipe with 4 inches of “bandwidth” so it can move more, …
