Did I miss something? They didn't mention why the new use case was slower. I was expecting some callback to that new usecase in the article somewhere. Always enjoy reading about performance debugging, thanks for writing this. Edit: they didn't talk about profiling either. It was an enjoyable read of rust serialisation for non rusty people though.

We use an in-product profiler (discussed here: https://www.feldera.com/blog/introducing-feldera's-visual-pr...), along with CPU profiles to identify where in the code we're spending time.
