console VS smol

tokio-console is a debugger for Rust async programs that use Tokio. To get started, add the console-subscriber crate to your project and add the following line which will initialise the subscriber and allow tokio-console to connect to it:

You could try https://github.com/tokio-rs/console to debug and profile what happens with tokio tasks in your program.

The tokio-console CLI is a fun one. The console-subscriber supports shipping to a console server running elsewhere, apparently. That gives you a window into what's happening now.

Tokio console maybe? https://github.com/tokio-rs/console

If I add "console_subscriber::init()" line as https://github.com/tokio-rs/console recommends, tracing_subscriber cannot be initialized.

I'm building an HTTP load tester called pdc! I have run out of obvious (to me at least) places to look for performance gains. I'm achieving around 45,000 requests per second, per core. Right now I'm using hyper with a separate tokio runtime (in current thread mode) running on each core. So far having runtime on each core/NUMA node has really helped with cache coherency. Any recommendations for profiling beyond tokio console or tokio metrics (Convenient timing amirite!)?

It was just an accident and has been fixed https://github.com/tokio-rs/console/issues/270.

P.S. Tokio [now also has Tokio Console](https://github.com/tokio-rs/console) allowing you to conveniently troubleshoot your tasks if they are causing issues :)

You can opt-in to async runtime such as tokio, and you can use tokio-rs/console for it's top-like metric

My understanding is you always need a runtime, somethings needs to drive the async flow. But there are others on the market, just not without the.. market domination... of tokio.

https://github.com/smol-rs/smol looks promising simply for being minimal

https://github.com/bytedance/monoio looks potentially easier to work with than tokio

https://github.com/DataDog/glommio is built around linux io_uring and seems somewhat promising for performance reasons.

I haven't played with any of these yet, because Tokio is unfortunately the path of least resistance. And a bit viral in how it's infected tings.

There is also https://github.com/smol-rs/smol which has components which you can compose into your own executor if you still need async IO but your usage patterns don't fit into the general purpose ones that Tokio provides.

If you need precise control over scheduling, consider building something on top of https://github.com/smol-rs/smol

Tokio is a "take what you need" framework, whilst Async-std started as an "everything the box" solution. Today both have a lot of crossover with micro async runtimes like smol becoming the foundation one of framework and optionally usable in the other. The ability to rip out a small dependent sub-crate (dependent package) like smol and use it independently with ease never get's boring, by the way. It's great way to include a test runtime in an async library without forcing the inclusion of a giant async framework.

Helix uses tokio. smol might be a good alternative however.

No, still active on GitHub. What gave you that idea? https://github.com/smol-rs/smol

Found the issue in Google cache. I'm not sure it's really fair of me to post this link here, but equally I think it's better to give the actual text rather than leave it vague.
