Article also states that the switch from C++ to Rust improves "low level optimized instruction sets, memory layout, and running async tasks."

The first two are also strengths of C++, and for the third the article says that "Rust is async, and Tokio is the one of the most popular async providers ... However, it’s not great for running CPU intensive workloads, like with Pinecone." Puzzling.

I've had more luck with async-std over Tokio for more CPU intensive workloads. But then again, I ran it on a kqueue platform so my experience is probably not representative.

My past experience with Rust async code is that both async-std and Tokio are fairly unimpressive on performance (as async code goes), particularly if you compare to ScyllaDB's runtime or other similar C++ async runtimes.
