At first glance, the market for mobile browsers looks roughly functional. Tech pundits and policymakers form expectations of browsers on the desktop and think about mobile browser competition the same way. The mobile ecosystem appears to retain these properties, but the resemblance is only skin deep. The Baseline Scenario #.

Just because everything works perfectly during production testing doesn’t mean that will be the case when your website is flooded with traffic. Bottlenecks can occur, for example, if you have a sudden surge in traffic that your servers are not equipped to handle. What Are the Benefits of Performance Testing?

This metric is important, but quite vague because it can include anything — starting from server rendering time and ending up with latency problems. This saves clients traffic — sometimes traffic which the client is paying for. This metric shows how much time it takes for the server to respond with something.

Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). Two-way latency is often called round-trip time (RTT).
