Show HN: Perf Sea – performance engineering for everyone https://ift.tt/wPnJehL

Show HN: Perf Sea – performance engineering for everyone I have found that many companies don’t have time for performance engineering and leave random tunables incorrectly configured for their workload. Instead of solving the same problems over and over I wanted an open source place where people could collaboratively share their best practices, knowledge, and methodologies, because in performance engineering no one is really a competitor. It is under active development, but currently you can: * scan flamegraphs to match with optimizations * scan raw hardware counter events to generate high level metrics and insights * scan arbitrary command output for system configuration red flags All in the browser with a simple copy paste. https://perfsea.com/ July 12, 2024 at 06:09PM
