我不太Get到你的意思, send cqe前有多少个unsignaled的请求不是固定的吗, 是` _local_window_capacity /
4`这个数值. 为什么不能确定呢.
同时brpc本身保证了一个Socket只会有一个bthread在写(即调用`CutFromIOBufList`,
其他的bthread只是把新的写请求加到队列当中), 那你这里提到的ibv_post_send的顺序跟记录unsignaled的顺序又是什么意思呢,
他们不是本来就是一致的吗
``` cpp
++_sq_unsignaled;
if (_sq_unsignaled >= _local_window_capacity / 4) {
// Refer to:
//
http::www.rdmamojo.com/2014/06/30/working-unsignaled-completions/
wr.send_flags |= IBV_SEND_SIGNALED;
_sq_unsignaled = 0;
}
ibv_send_wr* bad = NULL;
int err = ibv_post_send(_resource->qp, &wr, &bad);
```
