Performance is a huge subject, but it's not always a "back-end" or an "admin" subject: it's a Front-End responsibility too. The Front-End Performance Checklist is an exhaustive list of elements you should check or at least be aware of, as a Front-End developer and apply to your project (personal and professional). For each rule, you will have a paragraph explaining why this rule is important and how you can fix it. For more deep information, you should find links that will point to 🛠tools, 📖 articles or 📹 medias that can complete the checklist.

The APM Server receives data from APM agents and transforms them into Elasticsearch documents. It does this by exposing an HTTP server endpoint to which agents stream the APM data they collect. After the APM Server has validated and processed events from the APM agents, the server transforms the data into Elasticsearch documents and stores them in corresponding Elasticsearch indices.

Dynamometer is a tool to performance test Hadoop's HDFS NameNode. The intent is to provide a real-world environment by initializing the NameNode against a production file system image and replaying a production workload collected via e.g. the NameNode's audit logs. This allows for replaying a workload which is not only similar in characteristic to that experienced in production, but actually identical. Dynamometer will launch a YARN application which starts a single NameNode and a configurable number of DataNodes, simulating an entire HDFS cluster as a single application. There is an additional workload job run as a MapReduce job which accepts audit logs as input and uses the information contained within to submit matching requests to the NameNode, inducing load on the service.

Uses process.hrtime to capture marks + measures to gain deeper visibility into the timings that you define in your application. By default, the startTime of each mark is calculated by subracting the construction time from process.hrtime. If you would rather the startTime map as closely as possible to process.hrtime values, set offset: 0. You can also supply any number as a custom offset.

Small Magento 1 example extension that shows how Varien_Profiler information can be sent to the browser using the Server-Timing HTTP header so profiling info can be displayed e.g. by Google Chrome. Note: this is only an example, so don't use it in production! As soon as Varien_Profiler::getTimers() returns values they will be sent in the browser, no checking of IPs or similar going on.
