This Region will consist of three Availability Zones at launch, and it will provide even lower latency to users across the Middle East. I'm also excited to announce today that we are launching an AWS Edge Network Location in the United Arab Emirates (UAE) in the first quarter of 2018.

If the edit creates a new, unlogged network request, then the replay framework must inject new network events into the log. The paper contains a case study of the authors debugging EtherCalc using Reverb. Across the top 300 Alexa sites the gzipped logs have a median size of 45.4 KB (95%-ile size 113.2 KB), and it takes 7.8

eBPF was created by Alexei Starovoitov while at PLUMgrid (he's now at Facebook) as a generic in-kernel virtual machine, with software defined networks as the primary use case. Back then I could already tell if disks were seeking by interpreting iostat(1) output: seeing high disk latency but small I/O. eBPF does more.

Each stage has its unique challenges and potential pitfalls, as other case studies show. You need to beware that slow server response times can significantly increase TTFB, often due to server overload, network issues, or un-optimized logic on the server side. Here’s a breakdown of the moving pieces.

The use of server-timing headers by content delivery networks closes a big gap. Latency – How much time does it take to deliver a packet from A to B. Recent server timing case studies It's great to see server timing starting to get more use in the wild. But what happens when it doesn't? Definitely worth a read!

For example, in a case study published by Gilt Groupe , Eric Shepherd, who was formerly Gilt’s principal front end engineer, noted that: Both RUM and synthetic monitoring give different views of our performance, and are useful for different things. They each bring different – and complementary – information to the table.

A performance budget as a mechanism for planning a web experience and preventing performance decay might consist of the following yardsticks: Overall page weight, Total number of HTTP requests, Page-load time on a particular mobile network, First Input Delay (FID). Similarly, unoptimized images were the leading cause of page bloat.

Using an image CDN, such as KeyCDN, can significantly reduce the latency of your image delivery. This is crucial due to mobile devices requiring additional optimizations because they typically have less powerful hardware and a slower network connection when compared to desktop devices.
