Geofencing and geographic reachability testing for areas that are more challenging to access. For example, the ability to test against a wireless provider in a remote area. Performance testing based on variable metrics (i.e., connectivity, access, user count, latency) of geographic regions.

Low-latency Queries To avoid downloading all of the fact data from s3 in a spark executor and then dropping it, we analyzed our query patterns and figured out that there is a way to only access the data that we are interested in. Another learning is that we should have invested early into a robust testing framework.

We use this to debug errors and performance issues in specific mounts. Rerun a batch of replays We collect replays from actual MezzFS mounts in production, and we rerun large batches of replays for regression and performance tests. Adaptive Buffering — The shiny new technique described above.

Traditionally, we’ve spent a lot of time focusing on entitled groups as it relates to performance – fast connection speeds, devices with high-end CPUs, low-latency geographies. While you may say to yourself “nothing new here”, every day I see more and more opportunity to bring performance into the mainstream.

Testing helps in finding latency time of an application: Users prefer to use mobile phones over desktop when they are looking for any query, booking flight/movie ticket. Prioritize browser testing based on usage, market demand, highest traffic. Perform testing on browsers that are not frequently used by users.

The Lighthouse Performance score is based on some of the most important performance metrics : First Contentful Paint, First Meaningful Paint, Speed Index, Time to Interactive, First CPU Idle, and Estimated Input Latency. As we’ve discussed before , Lighthouse blends these performance metrics into a single composite score.

Many high-end disk subsystems provide high-speed cache facilities to reduce the latency of read and write operations.

In our own early tests , I found seriously diminishing returns at about 40 files. Finally, not inlining resources has an added latency cost because the file needs to be requested. Even then, however, validating protocol performance with the current generation of tools won’t be easy. Tools and Testing.
