Ask HN: What is the most difficult server performance problem you have debugged
1 point by jdesfossez on Aug 18, 2015 | hide | past | favorite
Hi, I am working on an open source efficient kernel-level latency tracker (I/O, CPU, scheduling, IRQ, etc), and I am looking for feedback from the community. I would like to know what are the hardest to debug server performance problems you have faced. The goal is to automate the detection of these problems at runtime. Thanks !
