ASP.NET的优化部署

1. machine.config
   位置：<system.web>，以下配置项数值对应CPU逻辑核心。

   <processModel enable="true" maxWorkerThreads="500" maxIoThreads="500" minWorkerThreads="250" minIoThreads="250" />

2. Aspnet.config
   以下是默认值，根据业务情况可不改

   <configuration>  
     <system.web>  
       <applicationPool   
           maxConcurrentRequestsPerCPU="5000"  
           maxConcurrentThreadsPerCPU="0"   
           requestQueueLimit="5000" />  
     </system.web>  
   </configuration>

3. IIS设置
   位置：服务器下的ASP属性
   
4. 应用程序池
   

WCF的优化部署

1. Web.config
   用来设置并发优化，对应CPU逻辑核心

   <system.serviceModel>
      <behaviors>
        <serviceBehaviors>
          <behavior>
            <serviceThrottling
              maxConcurrentCalls="100"
              maxConcurrentInstances="100"
              maxConcurrentSessions="100"
              />
          </behavior>
        </serviceBehaviors>
      </behaviors>
    </system.serviceModel>
   

ASP.NET的回收相关

1. 应用程序池不要设定定期回收，以免用户正在使用时发生回收
   

作为客户端时连接数的增加

1. Machine.config或app.config或web.config

   <configuration>
     <system.net>
       <connectionManagement>
         <add address = "*" maxconnection = "500" />
       </connectionManagement>
     </system.net>
   </configuration>
