boost::asio is a C++ library that provides asynchronous I/O operations to handle network programming, such as sockets and protocols. When working with boost::asio, the library will automatically manage the I/O operations in a non-blocking way, which means that it will not block the processor when waiting for I/O.
When boost::asio is not processing any I/O operations, it will go into an idle state. During this time, the processor will be free to execute other tasks, since boost::asio does not use a busy wait loop while idle. When new I/O operations occur, boost::asio will wake up and execute the appropriate handlers, which may involve utilizing the processor again.
In this way, boost::asio is designed to be very efficient with processor resources, making it a good choice for high-performance network programming applications.
