The presentation discusses a family of simple performance models that I developed over the last 20 years — originally in support of processor and system design at SGI (1996-1999), IBM (1999-2005), and AMD (2006-2008), but more recently in support of system procurements at The Texas Advanced Computing Center (TACC) (2009-present).

Edgar helps Netflix teams troubleshoot distributed systems efficiently with the help of a summarized presentation of request tracing, logs, analysis, and metadata. The more complex a system, the more places to look for clues. In an earlier blog post, we discussed Telltale , our health monitoring system. What is Edgar?

In technical terms, network-level firewalls regulate access by blocking or permitting traffic based on predefined rules. At its core, WAF operates by adhering to a rulebook—a comprehensive list of conditions that dictate how to handle incoming web traffic. You've put new rules in place. Let's dive deep into these challenges.‍1.

Last time around we looked at the DeathStarBench suite of microservices-based benchmark applications and learned that microservices systems can be especially latency sensitive, and that hotspots can propagate through a microservices architecture in interesting ways. Distributed tracing and instrumentation.

Using a global ASP as a benchmark can further mislead thanks to the distorting effect of ultra-high-end prices rising while shipment volumes stagnate. CrUX data collection and first-party RUM analytics of these metrics require live traffic, meaning results can be predicted but only verified once deployed. A 2021 Global Baseline.

They can also highlight very long redirection chains in your third-party traffic. They are more of a benchmark than a true measurement of real user experience. RUM systems embed a small JavaScript payload onto every page of your site. It might also not work well with a tag manager system if that’s a part of your architecture.

Only teams that master their systems can make intentional trade-offs. Panglossian nonsense. --> Organisations that serve their tools tread water no matter how advanced their technology, while groups that intentionally manage systems can succeed on any stack. [1]. Performance isn't a binary and there are no silver bullets.

Budgets are scaled to a benchmark network & device. Tools and CI systems help them monitor progress & prevent regressions. One distinct trend is a belief that a JavaScript framework and Single-Page Architecture (SPA) is a must for PWA development. Deciding what benchmark to use for a performance budget is crucial.
