    • Standalone and cluster-based servers, including Web servers, control the amount of data processed concurrently by such servers to thereby control server operating performance. Each server preferably includes a dispatcher for receiving data requests from clients, and at least one back-end server for processing such requests. The dispatcher preferably maintains a persistent connection, or a set of persistent connections, with the back-end server, and forwards the data requests received from clients to the back-end server over the persistent connections. Thus, instead of maintaining a one-to-one mapping of back-end connections to front-end connections as is done in the prior art, the back-end connections can be maintained by the dispatcher and used repeatedly for sending data between the dispatcher and the back-end server. In this manner, back-end connection overhead is markedly reduced.
    • 独立和基于群集的服务器(包括Web服务器)控制这些服务器并发处理的数据量,从而控制服务器的运行性能。 每个服务器优选地包括用于从客户端接收数据请求的调度器和用于处理这些请求的至少一个后端服务器。 调度员优选地与后端服务器维护持久连接或一组持久连接,并且通过持久连接将从客户端接收的数据请求转发到后端服务器。 因此,不像现有技术那样维持后端连接到前端连接的一对一映射,而是可以由调度器维护后端连接,并重复使用以在调度器之间发送数据 和后端服务器。 以这种方式,后端连接开销显着降低。
