Crate tokio_io_pool[−][src]
This crate provides a thread pool for executing I/O-heavy futures.
The standard Runtime provided by tokio uses a thread-pool to allow concurrent execution of
compute-heavy futures. However, it (currently) uses only a single I/O reactor to drive all
network and file activity. While this trade-off works well for many asynchronous applications,
it is not a great fit for high-performance I/O bound applications that are bottlenecked
primarily by system calls.
This crate provides an alternative implementation of a futures-based thread pool. It spawns a
pool of threads that each runs a tokio::runtime::current_thread::Runtime (and thus each have
an I/O reactor of their own), and spawns futures onto the pool by assigning the future to
threads round-robin. Once a future has been spawned onto a thread, it, and any child futures it
may produce through tokio::spawn, remain under the control of that same thread.
