Reading time 8 min In a constantly changing environment, brands are likely to be iterating on sites and applications to make them bigger, faster, fancier, and more engaging while pushing the new and updated code out as quickly as possible. Without a set plan in place, any new script can damage performance, affecting user experience, and, therefore, business KPIs.

For the past two years, the performance.now() conference has been the most valuable performance event I've attended. So valuable, in fact, that I've made some of the talks the cornerstone of this list of performance resolutions for 2020. I'd love to know how many – if any – of these are on your list. As always, I'd love people's feedback!

Learn more about manual and automated testing! Quality is the true measure of product success. Poor user experience or application performance negates any advantages you achieve in delivery speed or production cost. Put simply, if it does not work, it is not worth producing. It is, therefore, critical to our product success that we can accurately measure and track test results to ensure our testing is delivering against our business goals.

The first metric in our Flow Metrics series is F low Velocity, a measure of productivity and one of the “money metrics”. It tells you how many items were completed over a given period of time (week or month over month). Tracking your Flow Velocity over time provides historical data for teams to see if their delivery rates have improved, helping teams to provide more accurate estimates/forecasts on how much work they can deliver.

One of the key tools that performance engineers have at their disposal is the Performance Budget: it helps us—or, more importantly, our clients—ensure that any performance-focused work is monitored and maintained after we’ve gone. By establishing an acceptable threshold, be that based on RUM data, bundle analysis, image weight, milestone timings, or any other suitable metric, we can be sure that new or unrelated bodies of work do not have a detrimental impact on the performance of our site.

We need to rethink the role of the programmer. Look for the industry to become more stratified and specialized. The programming world will increasingly be split between highly trained professionals and people who don’t have a deep background but have a lot of experience building things. The former group builds tools, frameworks, languages, and platforms; the latter group connects things and builds websites, mobile apps, and the like.

Turning software delivery data into IT and business intelligence is nothing new; it’s the 21st-century gold rush. Yet getting to this level of maturity is a herculean undertaking, especially for IT organizations looking to obtain accurate cross-tool reporting that provides them with business-critical insights into their software delivery. For many, obtaining the one source of truth into what is going on through ETL and custom reporting—chiefly in terms of compliance—is extremely labor-intensive

A client connects to PgBouncer with the exact same syntax it would use when connecting directly to PostgreSQL – PgBouncer is essentially invisible.
