@Palmr Looking forward to your help

[Palmr]

@wangshilong1996 there should be no issues creating multiple instances of the Disruptor in once service.

From your code examples I could imagine a game server? In that case you may indeed want different queues per-game so that activity in one game does not affect the latency of another.

Hopefully that answers the question.

An aside: I see you're using handleEventsWithWorkerPool which is removed in Disruptor v4. Something to consider if it's a long-term project

@Palmr During my testing, 6000 connections were tested, and I found that multiple instances had lost events, while one instance did not.

@Palmr During my testing, 6000 connections were tested, and I found that multiple instances had lost events, while one instance did not.在测试过程中，我测试了 6000 个连接，发现有多个实例丢失了事件，而有一个实例没有。

因为事件太多，环形缓冲区被覆盖了，解决方案就是自己每次加入环形缓冲区的事后，判断下环形缓冲区还有没有空位，没有的话就先放到自定义的无限制队列里。
