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

Here’s some predictions I’m making: Jack Dongarra’s efforts to highlight the low efficiency of the HPCG benchmark as an issue will influence the next generation of supercomputer architectures to optimize for sparse matrix computations. Jack Dongarra talked about the scores, and pointed out the low efficiency on some important workloads.

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. Processors and memory consume the most power on the server, followed by the power supply efficiency loss. CPU Utilization and Power Consumption (Source: Blackburn 2008).

When it comes to optimizing your website, images are generally the most important asset you should spend time on figuring out how to reduce in size and deliver in a more efficient way. Using an image CDN, such as KeyCDN, can significantly reduce the latency of your image delivery. For example, the query string ?width=600&quality=70

Our metrics at Google show a conflicted picture (which I’m working to get to clarity on). Contended, over-subscribed cells can make “fast” networks brutally slow, transport variance can make TCP much less efficient , and the bursty nature of web traffic works against us. 75% of of connections occur on either 2G or 3G.

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. Large preview ).

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”.
