Benchmarks and reports for experimental-async-context-frame?

[ml1nk]

Hi there,

I use asynchronous context tracking in several of my Node.js projects, but the performance impact is always disappointing. The pull request "lib: rewrite AsyncLocalStorage without async_hooks" (nodejs/node#48528) should solve this problem, and was finally merged and released in Node.js 22.7.0 in August.

The rework is currently hidden behind "--experimental-async-context-frame" (https://nodejs.org/docs/v22.11.0/api/cli.html#--experimental-async-context-frame).

Has anyone tried it and can report back?

I couldn't find anything on this topic and wonder if no one is using AsyncLocalStorage or cares for the performance improvement. At least the test case in a small project of mine are working fine in both implementations.
