  Discontinued Continuous Profiling Platform. Debug performance issues down to a single line of code [Moved to: https://github.com/grafana/pyroscope] (by pyroscope-io)

  

I might be a bit biased [0], but I feel like this is where profiling tools, and particularly continuous profiling tools shine. Sampling profilers look at stack traces X number of times per second resulting in a very low CPU overhead. And so essentially you're getting a very high precision trace. It's not exactly the same (e.g the order in which functions were called is not preserved), but can still be used for the same type of performance analysis.

For rust you can use eBPF to get these traces down to system calls. You can even profiler other people's software with it.

Visual Studio's built-in profiler is an ok sampling profiler. It doesn't give you a nice multi-thread view which is a huge advantage to a span based profiler.

MTuner is quite nice for debugging memory usage. Which is another gaping hole in the Rust ecosystem. https://github.com/milostosic/mtuner

Lots of tools generate data in a format viewable by the Chrome trace viewer. I think Chrome's tracer viewer is not great. Maybe someday someone will create a viewer for the format that's good. I get cranky when large traces don't render at 60fps. Web-based viewers are almost all very very slow and it makes me sad.
