红帽全球峰会19.2. 配置一个 Worker
worker 是 XNIO worker 实例。XNIO worker 实例是 Java NIO API 的抽象层，它提供管理 IO 和 worker 线程等功能，以及 SSL 支持。默认情况下，JBoss EAP 提供一个名为 default 的单个 worker，但可以定义更多工作程序。
更新现有工作节点
更新现有的 worker：
/subsystem=io/worker=default:write-attribute(name=io-threads,value=10)
/subsystem=io/worker=default:write-attribute(name=io-threads,value=10)reload
reload创建新 worker
要创建新 worker，请执行以下操作：
/subsystem=io/worker=newWorker:add
/subsystem=io/worker=newWorker:add删除一个 Worker
删除 worker：
/subsystem=io/worker=newWorker:remove
/subsystem=io/worker=newWorker:removereload
