Load balancing : Traffic is distributed across multiple servers to prevent any one component from becoming overloaded. Load balancers can detect when a component is not responding and put traffic redirection in motion. Failure detection : Monitoring mechanisms detect failures or issues that could lead to failures.

One could argue this is a metric-driven decision. When they dug into the data, they found that the reason load times had increased was that they got a lot more traffic from Africa after doing the optimizations. How would you architecture a non-trivial size web project (client, server, databases, caching layer)?

As a discovery tool, request maps are great for identifying the source of third-party, fourth-party, fifth-party, etc., They can also highlight very long redirection chains in your third-party traffic. Poor performance of third-party services can have other business impacts even if your website does not use advertising.

One could argue this is a metric-driven decision.

This approach was touted to be better for fine-grained caching because each subresource could be cached individually and the full bundle didn’t need to be redownloaded if one of them changed. Note that there is an Apache Traffic Server implementation, though.). This is true, but only to a relatively limited extent.

For web-page loading, this slow-start approach can also affect metrics such as the first contentful paint, because only a small amount of data (tens of to a few hundred KB) can be transferred in the first few round trips. Examples include repeat visits on well-cached pages and background downloads and API calls in single-page apps.
