bbtree: fastest ordered map
How bbtree, a drop-in replacement for std's BTreeMap, cuts cache misses, instructions and cache coherence traffic, and how it is kept correct.
There's no reason for software to be slow anymore
📝 摘要 Dan Luu 论证 AI 编码智能体（coding agents）已将软件性能优化的成本降低了多个数量级——过去需要专业性能工程师数天/数周完成的工作，现在普通人输入几句话即可完成。文章通过多个案例展示这一趋势：FRE 正则引擎的 AOT 编译器切换为 ripgrep 带来 7% 提速；Azul 游戏 AI 借助 LLM 实现多线程和 10-20 项手工难以完成的优化，远超人工编写的…

Migrating LiteLLM to Rust - Building the Fastest and Litest AI Gateway
LiteLLM is moving its AI gateway to Rust: 15x throughput, 11x less memory, and sub-1ms per-request overhead. No v2, no migration, your config stays the same.
Building and operating a pretty big storage system called S3
Three distinct perspectives on scale that come along with building and operating a storage system the size of S3.
