Colleagues/Internet I love using [Linux performance tools]. But I also love solving issues quickly, and sometimes that means just asking colleagues or searching the Internet. Measuring the speed of time Is there already a microbenchmark for os::javaTimeMillis()? Microbenchmark os::javaTimeMillis() on both systems.

From day-to-day conversations to tech conferences, it’s not a topic that gets much air time. And for many internet-era companies, developing quality products at speed is necessary to gain market share and avoid being disrupted. I’m surprised that we don’t talk about incentives more often.

Earlier this month I spent a week at the OpenStack conference. But once you realize that there are, in fact, several OpenStack conferences happening at the same time and place, it makes more sense. Bear in mind that the internet currently takes 4ms from New York to Philadelphia.

The area he was in was served by satellite internet access, and experienced significant latency (a floor of 506 milliseconds) and packet loss (between 50-80% was typical). A local caching server, meant to speed up commonly-requested sites and reduce bandwidth usage, is a “man in the middle”.

Then, gather and share RUM data alongside business metrics to build support and ask, “Are there ways – without disrupting the overall functionality of the site – that we can speed things up a little bit?”.

Google do strongly encourage you to focus on site speed for better performance in Search, but, if you don’t pass all relevant Core Web Vitals (and the applicable factors from the Page Experience report) they will not push you down the rankings. While Core Web Vitals can help with SEO, there’s so much more to site-speed than that.

The success of our early results with the Dynamo database encouraged us to write Amazon's Dynamo whitepaper and share it at the 2007 ACM Symposium on Operating Systems Principles (SOSP conference), so that others in the industry could benefit. As we say at AWS, It is still Day One for DynamoDB.

Most of us work on connections that are typically quite a bit faster than that of the average internet user. In the early days of the web when we were browsing the internet via a dialup connection, improving performance meant removing the images from your site. I think this myth stems more from a lack of awareness. 21% less searches.

Today, this makes concurrency more important than ever, because it delivers two things: It hides latencies we have to deal with and cannot remove, from disk I/O latency to speed-of-light network latency; and it makes our code responsive by not introducing needless latencies of our own even when we’re not hiding someone else’s latency.

One of the most significant announcements of the entire conference to me was that of per-function concurrency control. That means that 3GB functions might not see a linear speed bump for primarily single threaded functions.

Both Xen and KVM have had many performance and security improvements, and workloads can now be tuned to run at almost bare metal speeds (say, a 3% loss or less). The odd time we hit them, we'll take the "oops message" – a dump of the kernel stack trace and other details from the system log – and search the Internet.
