DeepSeek 3FS Performance Journal
A series analyzing the filesystem (3FS) DeepSeek uses for LLM training and inference
- Introduces 3FS, its claims and high‑level design
- Reviews DeepSeek’s published graphs against theoretical limits
- Builds and evaluates network and storage microbenchmarks ~ asking how does it perform in practice
Highlighted Posts
- Describes the process of building an end‑to‑end pipeline for scraping/decoding League of Legends replays. Datasets: 700K+ and 700K+ (S12).
- Intercepts OpenGL pipelines and re‑renders them with NVIDIA ray tracing (and its many various difficulties)
- Measuring cloud storage and network performance for LLM training pipelines
