That is a lot of text for not determining why the new solution is faster. The only relevant part:

> Before our migration, the old pipeline utilized a C library accessed through a Python service, which buffered and bundled data. This was really the critical aspect that was causing our latency.

How much speed up would there have been if they moved to a Rust wrapper around the same C library?

Using something other than Python is almost always going to be faster. This Reddit post does not give any insights into which aspects of Python lead to small/large performance hits. They show that it was the right solution for them with ample documentation which is great, but they don't provide any generalizable information.
