I remember reading articles about how 3G connectivity was going to transform performance and, more generally, the way we used the internet altogether. To be fair, each new generation of network connectivity does bring some level of change and transformation to how we interact with the internet. And those speeds aren’t constant.

Everyone who is old enough to remember the sound of connecting to the Internet with a dial-up modem or of AOL announcing that "You've got mail" is acutely aware that there is an upper limit to how fast something can be downloaded, and it never seems to be as fast as we would like it. The big challenge is that we must strike a balance.

During our testing using the storage optimized EC2 instances (I3.2xlarge) we noticed that we were able to perform over 200K IOPS of 1K byte items thus meeting our throughput goals with latency rarely exceeding 1 millisecond.

DNS, which stands for domain name system , is an Internet service that translates domains names into IP addresses. You can think of a DNS server as a phone book for the internet. Speed Speed also plays a role with DNS. Using a fast DNS hosting provider ensures there is less latency between the DNS lookup and TTFB.

HTML, CSS, images, and fonts can all be parsed and run at near wire speeds on low-end hardware, but JavaScript is at least three times more expensive, byte-for-byte. Many critiques are possible, both of the target (five seconds for first load), the sample population (worldwide internet users), and of the methodology (informed reckons).

Using an image CDN, such as KeyCDN, can significantly reduce the latency of your image delivery. As Sara Souedan said, not everyone has access to fast internet. For example, while the average mobile download speed on 4G in Switzerland is fast at 35.2 This means we need to always be testing for different devices and connections.

I had my website with funny photos and links to favorite websites live on the internet, and better yet, I could edit directly on the server.

This metric is important, but quite vague because it can include anything — starting from server rendering time and ending up with latency problems. For example, for an internet shop, it may be a page with a product list, product details page, shopping cart, checkout, and so on. Synthetic Tests. So make a competitors list.
