My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. Ford, et al., “TCP

This follow-up post revisits the question for SQL Server 2019, using a larger number of rows. I will be using the 50GB Stack Overflow 2013 database , but any large table with a low number of distinct values would do. The Stack Overflow 2013 database comes without nonclustered indexes to minimize download time. Test Environment.

Google has been working for quite some time to speed up its network protocols in order to minimize website response times. After HTTP/2 has fulfilled its task of speeding up HTTP(S) and has become the basis for fast TLS connections, QUIC goes one step further by aiming to replace the TCP transport protocol in the Internet.

When I first stumbled on the idea of skeleton screens, thanks to Luke Wroblewski talking about them back in 2013 , I latched onto them pretty quickly. Instead, they adjusted the design, switching from spinners to a skeleton screen that incrementally filled in as content arrived back from the server.

Even if you render components on the server and hydrate them on the client, it still churns because component hydration is computationally expensive. Server rendering is also cool—even if that’s just how we say “send HTML over the network” these days. A stateful Preact component, also server-rendered and hydrated on the client.

This reconfirms observations from the HTTP Archive , published by Steve Souders in 2013. Having worked on browsers for more than a decade, I think it would be shocking if a browser team agreed to more than 10 MiB for a feature like this, especially if it won't dramatically speed up the majority of existing websites.
