 Every team should be collecting telemetry metrics on it’s public API usage. This will be important for knowing when it’s safe to make breaking changes. The Core team will be looking into ways to make this easier and an automatic part of registration (see [#112291](https://github.com/elastic/kibana/issues/112291)).
 
+### APM
+
+Kibana server and client are instrumented with APM node and APM RUM clients respectively, tracking serveral types of transactions by default, such as `page-load`, `request`, etc.
+You may introduce custom transactions. Please refer to the [APM documentation](https://www.elastic.co/guide/en/apm/get-started/current/index.html) and follow these guidelines when doing so:
+
+- Use dashed syntax for transaction types and names: `my-transaction-type` and `my-transaction-name`
+- [Refrain from adding too many custom labels](https://www.elastic.co/guide/en/apm/get-started/current/metadata.html)
+
 ### Documentation
 
 Every public API should be documented inside the [docs/api](https://github.com/elastic/kibana/tree/main/docs/api) folder in asciidoc (this content will eventually be migrated to mdx to support the new docs system). If a public REST API is undocumented, you should either document it, or make it internal.

+## Server-side considerations
+
+### Don't block the event loop
+
+[Node.js is single threaded](https://nodejs.dev/learn/introduction-to-nodejs) which means a single CPU-intensive server-side, synchronous operation will block any other functionality waiting to execute on the Kibana server. The affects background tasks, like alerts, and search sessions, as well as search requests and page loads.
+
+**When writing code that will run on the server, [don't block the event loop](https://nodejs.org/en/docs/guides/dont-block-the-event-loop/)**. Instead consider:
+
+- Writing async code. For example, leverage [setImmediate](https://nodejs.dev/learn/understanding-setimmediate) inside for loops.
+- Executing logic on the client instead. This may not be a good option if you require a lot of data going back and forth between the server and the client, as that can also slow down the user's experience, especially over slower bandwidth internet connections.
+- Worker threads are also an option if the code doesn't rely on stateful Kibana services. If you are interested in using worker threads, please reach out to a tech-lead before doing so. We will likely want to implement a worker threads pool to ensure worker threads cooperate appropriately.
