The performance of web pages is an important topic for many IT managers. Speed, security, appearance, and reliability are common metrics for measuring performance. What is a mystery to many is what affects those metrics. The article, Web Performance Matters, Slowness Considered Harmful does a good job explaining key network influences on websites, common misconceptions about where problems lie, and general things that can be done to mitigate unchangeable network influences.
One key point the article makes is summed nicely in the following quote, “One concept that continues to elude many IT managers is the impact of latency on network design … Latency, not bandwidth, is often the key to network speed, or lack thereof.” from It’s the Latency Stupid, Stuart Cheshire.
