Questions with details

潘少你好，最近在我在用gnet接kcp，kcp是使用的udp通讯，我现在是在Traffic里创建kcp连接对象然后把收到的数据复制一份扔到kcp中，因为kcp需要外部时钟驱动，所以我用了OnTick作为外部时钟。

我想请教的问题有2个： 1、OnTick是不是一直被一同一个goroutine触发？ 2、我在OnTraffic里创建kcp对象并收包是否算阻塞操作，是否需要用ants来开多个goroutine处理？

创建kcp对象不是所有收包都要进行，如果是同一个来源的udp包，只会在首次收到包时创建这个kcp，后面就只是往这个kcp里扔数据了。
OnTick中还有一个功能就是负责检查和处理kcp连接的超时销毁工作

以上就是目前的遇到的问题，因为能力有限，阅读gnet源码后任然不知道结果，望指点

1. 是
2. 在 gnet 中涉及的阻塞操作通常是指可能会让内核将当前线程调离 CPU 并挂起休眠的 I/O 操作，通常是网络 I/O 或者磁盘 I/O，或者是其他可能会被内核阻塞挂起的操作，如果你只是做一些封包/解包的操作，而且期间只会访问内存，那就不是阻塞操作。

1. Yes
2. The blocking operations involved in gnet usually refer to I/O operations that may cause the kernel to transfer the current thread away from the CPU and suspend sleep, usually network I/O or disk I/O, or other operations that may be The kernel blocks pending operations. If you just do some packet/unpack operations and only access memory during the process, it is not a blocking operation.
