Workers and Durable Objects gain on-demand resource profiles
The news at the time
Cloudflare announced CPU and memory profiling for Workers and Durable Objects, with on-demand collection and downloadable profiles described in the article.
For CPU profiling, the implementation starts a V8 profiler with a one millisecond sampling interval. That sampling detail is not evidence of zero production overhead.
Follow-up checked during renewal
No additional follow-up fact was established in this renewal. This does not establish that nothing changed.
What to review before applying this
Check that the requested version and isolate are active at the selected location, and compare behavior with and without profiling under representative traffic. Resource allocation samples and retained memory are different questions.
Editorial review suggestions; no hands-on product experiment was performed.
