Many thanks for building and releasing this. It's ridiculously easy to install (especially in virtualenvs) and very powerful. When I push '3' or '4', I get informative, stable output.

Minor feature request: an explicit 'pause' button would make it easier to copy file paths from the output. Ctrl-S is a reasonable alternative, but it's a little hacky.

Also, it would be nice to somehow eliminate time spent in poll() from the results. I'm profiling a server process and 99.9% of the time is spent in a poll function. Perhaps there could be an option to disregard time spent in system calls rather than user code. Most of the time I'm interested in profiling only user code.

(Actually, I've been looking for a reason to play with Rust code. Maybe I'll try to add these features myself!)

Thanks! Both of your suggestions totally make sense. I've created an issue to track the poll() issue here https://github.com/benfred/py-spy/issues/13 - I think that should be an easy fix.

I think a more robust solution might be to have counters for in-Python samples, outside-Python, and in-syscall.
