Dan Luu 写系统问题时，习惯先测量、再对照、最后才下结论。把「Slowlock」放到智能体、评测和线上系统里，真正要问的是：默认做法会不会系统性失败。下面用中文整理成可执行的工程笔记，去掉原站导航和无关链接。

Conclusion

Every once in awhile, you hear a story like “there was a case of a 1-Gbps NIC card on a machine that suddenly was transmitting only at 1 Kbps, which then caused a chain reaction upstream in such a way that the performance of the entire workload of a 100-node cluster was crawling at a snail's pace, effectively making the system unavailable for all practical purposes”. The stories are interesting and the postmortems are fun to read, but it's not really clear

The situation reminds me of distributed systems failures before Jepsen . There are lots of anecdotal horror stories, but a common response to those is “works for me”, even when talking about systems that are now known to be fantastically broken. A handful of companies that are really serious about correctness have good tests and metrics, but they mostly don't talk about them publicly, and the general public has no easy way of figuring out if the systems th

落地时建议先做的 5 件事

1. 用自己的真实负载测，而不是只用公开榜或厂商数字。
2. 把评测设计成能抓到失败模式：平均分好看但尾部崩溃，仍然算失败。
3. 智能体默认不会好好用测试；要写进流程，而不是写在口头规范里。
4. 性能和正确性都要有基线，改模型或改语言前后必须能对比。
5. 结论写成可回滚的决策：哪一版配置、哪一版评测集、谁签字。

和智能体产品怎么接

龙虾PRO做 OpenClaw 落地时，同样吃「先测量再扩面」这条纪律：技能、数字员工和网关都要有可复现评测，而不是只看一次演示通过。

本文侧重全链路风控方法论。落地时请用自身业务单据做回放验证，不要把示例阈值直接当生产策略。 相关：风控体检 · 方案资源
