What I like about profiling.tracing is how you can control it in the same code base that you are profiling. That turns tracing into a feature you can ship, not just a tool you can attach. Profiling.sampling doesn't seem to provide anything similar, it has to run as a separate process

I'm not trying to criticize, but Python is known to be much slower than eg. Java or Go etc. So for performance-critcal code, why use Python? I find Python to be very good because it is concise and simple, but I have not used it for production so far.

This sounds a lot like py-spy. How does it compare?

Interesting, does wall-time mode work with Asyncio?
Imagine if I have a single request calling asyncio.gather() on 5 different coroutines. Only 1 is on CPU, the other 4 are on IO. Is Tachyon able to sample all 5 coroutine tasks?
