请问nb采用jetty容器启动，性能如何，是默认nio还是bio，并发如何，有人测试过没

@wendal 我看了jettyStarter的源码，看不出是不是启用的nio，能指导下吗？另外想知道默认的最小线程数20，最大500，是有什么依据或经验吗，如果服务器配置和网络带宽高，这个有没有向上调整提升并发量的可能，另外，如果同意台机器多实例运行，能否提高并发量呢，能否讨论下，谢谢！
首先, NIO的问题: https://www.eclipse.org/jetty/documentation/9.4.x/quickstart-config-what.html "which is NIO based"
Prior to Jetty 9, the type of the connector reflected both the protocol supported (HTTP, HTTPS, AJP, SPDY), and the nature of the implementation (NIO or BIO). From Jetty 9 onwards there is only one prime Connector type (ServerConnector), which is NIO based and uses Connection Factories to handle one or more protocols.
