My home internet connection gives me somewhere around 3 Mbps down. Mbps download speed Jake Archibald mentioned his relative getting or the 0.8 Mbps download speed my in-laws get at their house. It seems blazingly fast compared to the 0.42 It’s not just the short shelf-life of devices that is impacted by poor performance.

It has been since 2016 that a major IT firm WIPRO has been pushing for the application of hyper-automation to all their processes in their own firm. IoT or Internet of Things is an example of that. Some stats that prove that user experience should not be taken lightly ever: 80% of all internet users own a smartphone.

In the late 1990s, marketing and advertising agencies saw the potential of eye-tracking for the Internet and started using the technology to analyze how people consume content online.

I wrote a blog in 2016 that discussed the need for businesses to flip the traditional monitoring investment pyramid on its head. Paul Calvano has an awesome post using HTTP archive data to detail the prevalence of third party content on the internet. Third parties are a huge necessity and problem for digital businesses.

Here's what loading 14 scripts looked like in Internet Explorer 7: I've added a red arrow at the beginning of each script request. Browsers added support for this attribute starting with Firefox and Chrome in 2010, followed by Safari and Internet Explorer in 2012. The number of sync dropped and async rose in June 2016.

I wrote a page on it: [perf]. - **eBPF**: tracing features completed in 2016, this provides efficient programmatic tracing to existing kernel frameworks.

That means that 3GB functions might not see a linear speed bump for primarily single threaded functions. API Gateway can now be used to provide an internet-accessible public front to web services enclosed within a VPC. We plan to test this out when we get the chance. As such I was excited to see X-Ray introduced last year.
