As developers, we rightfully obsess about the customer experience, relentlessly working to squeeze every millisecond out of the critical rendering path, optimize input latency, and eliminate jank. On top of this foundation, we add layers of caching, prerendering and edge delivery optimizations — not the other way around.

As data centers and volumes of servers have grown, so has the overall amount of electricity consumed around the world. Without effective caching on the client, the server will see an increase in workload, more CPU usage and ultimately increased latency for the end user. This is where service workers can make a difference.

This rework delays launch which, in turn, delays gathering data about the viability of a PWA strategy. Our metrics at Google show a conflicted picture (which I’m working to get to clarity on).

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).

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. For example, you could reduce compression efficiency , because that works better with more data. Implementation.
