This module answers three questions before you start:
| File | Description |
|---|---|
how-to-use-this-system.md | Navigation guide, module dependency map |
learning-path.md | Detailed paths for each experience level |
prerequisites.md | What to know before starting each module |
Most backend performance problems are not framework problems. They are computer science problems that manifest at the framework layer.
When an API is slow because of N+1 queries, the fix is not "upgrade your ORM". The fix is understanding why O(N) queries is worse than O(1) — an algorithms problem — combined with understanding that each query crosses the network — a networking problem. Both of those root causes are covered in BSPS.
Read how-to-use-this-system.md first. Then prerequisites.md to assess where you are. Then learning-path.md to choose your path.
