# coroutines

What is the impact of running the coroutines debug agent in production? I find it really useful to do kill -5 to get insight into the running coroutines, but always see the "do not use in production" warnings.

the debug agent itself needs to grab a stack trace every time you create a coroutine, and probably also when it resumes, which is quite expensive if you have a lot of suspending coroutines

[octylFractal]

if you also like using the non-agent debug features, those cause a call to Thread#setName every single time it changes threads

Thx, sounds like the warnings were accurate 🙂

You can keep track of the issue in https://github.com/Kotlin/kotlinx.coroutines/issues/1379

If you have concerns about setName, please left them in the comments

Oh yeah, I forgot I'm the one that created that issue (and you moved it to GitHub for me) 🙂
