FlameGraph VS comlink

We'll use async-profiler and flame graphs for profiling. To simplify the process, we'll run the code using JBang.

And flame graphs excel and this kind of thing

which can output in a format understood by Brendan Gregg's flame frames (https://www.brendangregg.com/flamegraphs.html)

But that's not quite the kind of tracing you're talking about. We also built a printf-style interface to our recording files, which seems closer:

Strategies included discontinuing or resizing underutilized services, transitioning to more cost-effective solutions, reducing the current resources to the amount of resources that we need for our application, and conducting detailed analyses of computing resource utilization through tools like flamegraphs. This detailed scrutiny helped identify and rectify significant cost-driving areas, such as garbage collection and application configurations.

Flame Graphs by Brendan Gregg

Historically brendangregg's since AIUI he basically invented flamegraphs

https://www.brendangregg.com/flamegraphs.html

So if you can make your tool eat whatever https://github.com/brendangregg/FlameGraph is fed with you're going to support a lot of existing tooling across OSes and languages.

“Flame graphs are a visualization of hierarchical data, created to visualize stack traces of profiled software so that the most frequent code-paths to be identified quickly and accurately.”

SVGs are amazing for interactive visualisation too. Like Flamegraphs: https://www.brendangregg.com/flamegraphs.html

This may be a good example of the application of a flame graph but it is not a good demonstration of flame graphs; the graph is nearly incidental. The source has an actual explanation.

A profiling flame graph from Graphile Crystal (a precursor to Grafast) using GraphQL.js' executor (each tick is 1ms, total: 29ms). As we removed more and more responsibilities from GraphQL.js, we ended up only using it for output. Replacing this final responsibility with a custom implementation in Graphile Crystal itself, we reduced execution time for this query down to 15.5ms (effectively removing the majority of the yellow portion of the flame graph).

Feels like taking a general Comlink-like system & making it more component oriented. Good ideas. https://github.com/GoogleChromeLabs/comlink

Reminds me of Comlink

Now that we have a way to create PDF files, we can create a web worker to run the renderPDF function in a separate thread. Here’s an example of a web worker that uses comlink to expose the renderPDF function as an asynchronous function:

To streamline the process of configuring the Service Worker and simplify communication between the app and the Service Worker, we will be using the comlink library.

While there's no realistic way to provide a security boundary between JavaScript modules, Workers are a possibility [1].

The code with the more restricted set of permissions must run in the Worker. That code then communicates with the rest of your app through postMessage / SharedArrayBuffer, perhaps using ComLink [2].

The worker API is very simple, you would post a message to the worker. The worker would have the code to process and reply back with the results to the listeners. To make it even easier Google has created the comlink library.
