Site performance is potentially the most important metric. The better the performance, the better chance that users stay on a page, read content, make purchases, or just about whatever they need to do. With all of this in mind, I thought improving the speed of my own version of a slow site would be a fun exercise. Lighthouse.

A co-worker introduced me to Craig Hanson and Pat Crain's performance mantras, which neatly summarize much of what we do in performance analysis and tuning. They are: **Performance mantras**. These have inspired me to summarize another performance activity: evaluating benchmark accuracy. Don't do it. Do it less.

Moreover, just like an A/B test, we’ll be collecting metrics while the experiment is underway and performing statistical analysis at the end to interpret the results. degraded hardware, transient networking problem) or, more often, because of some change deployed by Netflix engineers that did not have the intended effect.

It’s another networking paper to close out the week (and our coverage of SOSP’19), but whereas Snap looked at traffic routing within the datacenter, Taiji is concerned with routing traffic from the edge to a datacenter. For example, balance utilisation across all data centers, or optimise for network latency. SOSP’19.

There are many possible failure modes, and each exercises a different aspect of resilience. Collecting some critical metrics at one second intervals, with a total observability latency of ten seconds or less matches the human attention span much better. A resilient system continues to operate successfully in the presence of failures.

At the start of November I was privileged to attend HPTS (the High Performance Transaction Systems) conference in Asilomar. Therefore any programming abstraction must be low latency and the kernel needs to be kept off the path of persistent data access as much as possible. Early performance results. PLOS’19.

during a typical week at Netflix, MezzFS performs ~100 million mounts for dozens of different use cases and streams about ~25 petabytes of data. We use this to debug errors and performance issues in specific mounts. More on this below… Adaptive buffering ?—?More How much faster is this?
