If we had an ID for each streaming session then distributed tracing could easily reconstruct session failure by providing service topology, retry and error tags, and latency measurements for all service calls. Additionally, it became easy to provide deep links to different monitoring and deployment systems in Edgar due to consistent tagging.

As businesses compete for customer loyalty, it’s critical to understand the difference between real-user monitoring and synthetic user monitoring. However, not all user monitoring systems are created equal. What is real user monitoring? RUM gathers information on a variety of performance metrics.

For example HammerDB has not used tpmC terminology to report TPC-C based metrics instead using TPM and NOPM nomenclature. The HammerDB TPROC-C workload by design intended as CPU and memory intensive workload derived from TPC-C – so that we get to benchmark at maximum CPU performance at a much smaller database footprint.

Before you begin tuning your website or application, you must first figure out which metrics matter most to your users and establish some achievable benchmarks. Quantitative performance testing looks at metrics like response time while qualitative testing is concerned with scalability, stability, and interoperability.

In this session, we discuss the technologies used to run a global streaming company, growing at scale, billions of metrics, benefits of chaos in production, and how culture affects your velocity and uptime. Netflix runs dozens of stateful services on AWS under strict sub-millisecond tail-latency requirements, which brings unique challenges.

A performance budget is a threshold that you apply to the metrics you care about the most. A performance budget is a threshold that you apply to the metrics you care about the most. Which metrics should you start with? With hundreds of potential performance metrics to track, this is a huge question. Let's get started!

In an earlier blog post, we discussed Telltale , our health monitoring system. Tracing as a foundation Logs, metrics, and traces are the three pillars of observability. Telltale provides Edgar with latency benchmarks that indicate if the individual trace’s latency is abnormal for this given service.

This is a complex topic, but to borrow from a recent post , web performance expands access to information and services by reducing latency and variance across interactions in a session, with a particular focus on the tail of the distribution (P75+). Consistent performance matters just as much as low average latency.

Budgets are scaled to a benchmark network & device. Tools and CI systems help them monitor progress & prevent regressions. This helps support executive sponsors who then have meaningful metrics to point to in justifying the investments being made. Deciding what benchmark to use for a performance budget is crucial.
