necessary to make task schedulable between threads. For example, if we were to write a load balancer like NGINX, we would write it in a thread-per-core way. The thread local data does not need to be shared between threads, so theSyncandSenddo not need to be implemented in the first ...
在runtime中有 runtime.LockOSThread 和runtime.UnlockOSThread 两个函数,这两个函数有什么作用呢?我们看一下标准库中对它们的解释。 runtime.LockOSThread // LockOSThread wires the calling goroutine to its current operating system thread. // The calling goroutine will always execute in that thread...
作为一个基于 io_uring/epoll/kqueue 的 Runtime,Monoio 目标是在兼顾平台兼容性的情况下,做最高效、性能最优的 thread-per-core Rust Runtime。 我们的出发点很简单:跨线程任务调度会带来额外开销,且对 Task 本身有Send和Sync约束,导致无法很好地使用 thread local storage。而很多场景并不需要跨线程调度。如ngi...
