tokio-io-pool's Introduction

tokio-io-pool

This crate provided a thread pool for executing short, I/O-heavy futures efficiently.

It is no longer necessary following the scheduler improvements in tokio 0.2.0-alpha.7, which handle concurrent I/O on many sockets much better than the old scheduler did. Tokio 0.2 also does not allow the same hooks to provide a custom scheduler, so even if it were necessary, updating tokio-io-pool to work as "transparently" as it did with tokio 0.1 would be difficult. For that reason, this project has been discontinued. If you find an issue with tokio's performance, file it as a tokio bug :)

No Timer/Reactor per thread: Uses CurrentThread Runtime with ParkThread Park impl

Currently it looks like tokio-io-pool uses the default Park of CurrentThread, which is ParkThread. That one is basically a condition variable and nothing else.

That means, from what I understand, that a global Reactor (and Timer) instance is created, and not one per thread.

AFAIU to have one reactor per runtime, something like the following would be needed

    let reactor = reactor::Reactor::new().unwrap();
    let handle = reactor.handle();
    let mut enter = ::tokio_executor::enter().unwrap();
    let timer = timer::Timer::new(reactor);
    let timer_handle = timer.handle();
    let mut current_thread = tokio_current_thread::CurrentThread::new_with_park(timer);

    ::tokio_reactor::with_default(&handle, &mut enter, |mut enter| {
        ::tokio_timer::with_default(&timer_handle, &mut enter, |enter| {
            current_thread.run();
        }
    }
