I haven't known about such a big resource consumption of DI

In the previous thread, Litestar's RPS dropped 36% with 2+ flat dependencies due to TaskGroup overhead. 📉

How do #Litestar and #FastAPI perform with real DB queries in dependencies? Let's figure it out in this thread 🧵

Summarized my findings and opened an issue. Hoping to help make #LiteStar just a little bit better.

Is #LiteStar faster than #FastAPI? Benchmarks say yes, but look at Dependency Injection. 📉

Adding just 2 flat dependencies significantly degrades the throughput. I dug into the source to find why.

Thread: TaskGroups, Kahn's algorithm & performance trade-offs. 🧵

A bar chart titled "LiteStar" showing Request Per Second (RPS) performance across different numbers of dependencies (0 to 5). The RPS drops from 41,451 with 1 dependency to 26,492 with 2 dependencies. A red arrow points to this 36% decrease with a handwritten caption asking "Why?".
