Boost.Asio VS asyncio

Indeed looks like it, strand_executor_service.hpp is using a Mutex internally (otherwise it wouldn't make sense to me).

as a side note, Asio is also released as an independent library without the boost stuff https://think-async.com/Asio/

Now that vinniefalco is going to kill off the asio standalone (see deprecate standalone ) and only support boost what would people then recommend to switch over to.

The ASIO framework can be found at https://think-async.com/Asio/ and the relevant license for its use is included in the GitHub repository in the Vendor/licenses directory.

The library is found at https://think-async.com/Asio/.

Asio Extracted from the much bigger Boost C++ library, it's apparently a really good networking library. As a bonus it also handles async / threads. Here's a really good video tutorial by OneLoneCoder

Yes: https://github.com/chriskohlhoff/asio/blob/master/asio/include/asio/coroutine.hpp

Here's the main contributor to Asio. I looked at Asio's repository and this was the first guy.

I publish my coroutine library: asyncio(https://github.com/netcan/asyncio) that imitate python asyncio, some people may be interested in the performance of c++20 coroutine features, so I benchmark my library in localhost, and in terms of comparisons with other methods.
