参考这个 benchmark,分别对不同的 ThreadPool 进行测试,在我的机器上面会发现 crossbeam 的性能会明显好很多,标准库 channel 其次,最后才是 condition variable。 test thread_pool::benchmark_condvar_thread_pool ... bench:128,924,340 ns/iter (+/-39,853,735) test thread_pool::benchmark...
title: rust scoped thread pool date: 2021-08-09 16:53:11 用rayon即可。 mod a { fn fun(a: &mut i32) -> i32 { *a += 1; return *a + 233; } pub fn main
futures有两种executor:LocalPool和ThreadPool。 本文介绍ThreadPool。 对于ThreadPool,它通过把任务提交到线程池,然后让一组固定的线程去执行任务,并且为每一个任务增加了状态机,从而实现了异步的方式。 我们来看看ThreadPool的代码: /// A general-purpose thread pool for scheduling tasks that poll futures to /...
