Ever wondered how a profiler knows which JavaScript function is hot when V8 compiles your code three different ways? Brennan went deep on unwinding and symbolizing V8 stacks across Sparkplug, Maglev, and TurboFan. The detective work behind every flame graph. 🔥 www.polarsignals.com/blog/posts/2...

Polar Signals@polarsignals.com · 2mo ago🚀 Launching today: GPU PC sampling in production. Instruction-level profiling telling you why and where warps stall. Whether it is memory latency, scoreboard waits, or barriers. 🧊 Previously NSight-only territory. Now running in prod with low overhead. www.polarsignals.com/blog/posts/2...
Very excited for this year's #FOSDEM! Lots of talks by Polar Signals folks:
Are USDTs the key to unlock the future of low level tracing? Maybe! Read all about how we implemented them and how we plan on using them to breath new life into observability! www.polarsignals.com/blog/posts/2...
