Using an image CDN, such as KeyCDN, can significantly reduce the latency of your image delivery. For example, while the average mobile download speed on 4G in Switzerland is fast at 35.2 Mbps, countries with a growing Internet users like India is only at an average mobile download speed of 6.8 Mbps ( Opensignal ).

A then-representative $200USD device had 4-8 slow (in-order, low-cache) cores, ~2GiB of RAM, and relatively slow MLC NAND flash storage. The fastest Androids predictably remain 18-24 months behind, owing to cheapskate choices about cache sizing by Qualcomm, Samsung Semi, and all the rest. The Moto G4 , for example. Is that a lot?

Because of the redirection, our total HTML request, download, and render time took an additional 156 ms – for a total of 521 ms. If your site requires external files, such as images and CSS, ensure that your HTML calls these resources directly and that there aren’t any redirects occurring to download these files.

Script execution delays interactivity in a few ways: If the script executes for more than 50ms, time-to-interactive is delayed by the entire amount of time it takes to download, compile, and execute the JS. 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).

You’ve probably heard things like: “HTTP/3 is much faster than HTTP/2 when there is packet loss”, or “HTTP/3 connections have less latency and take less time to set up”, and probably “HTTP/3 can send data more quickly and can send more resources in parallel”. IETF’s QUIC is technically very different from Google’s QUIC.

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. Finally, not inlining resources has an added latency cost because the file needs to be requested. Prioritization. Implementation.
