In this article, I share the challenges I faced when trying to profile requests in an asynchronous FastAPI server. The traditional profiler, cProfile, provided inaccurate results due to the nature of asynchronous functions, which resulted in misleading statistics.

I quickly started to realize that some of these asset packs caused the tag list to be filled with entries that weren't linked to any assets at all. This made the asset discovery process quite frustrating.
