ASP.NET Processmodel 配置优化

Question

常规 ASP.NET 安装将使用以下配置创建 machine.config:

<system.web>
    <processModel autoConfig="true" />  

我想覆盖 web.config 中的一些属性值，例如:

<system.web>
   <processModel 
     maxWorkerThreads="100" 
     maxIoThreads="100" 
     minWorkerThreads="40" 
     minIoThreads="30" 
     memoryLimit="60" 
   />

我想知道是否必须将所有默认属性写入 web.config 中，还是会自动从 machine.config 中获取 processmodel 的其他默认属性？

以下是processmodel的属性

<processModel 
   enable="true|false"
   timeout="hrs:mins:secs|Infinite" 
   idleTimeout="hrs:mins:secs|Infinite"
   shutdownTimeout="hrs:mins:secs|Infinite"
   requestLimit="num|Infinite"
   requestQueueLimit="num|Infinite"
   restartQueueLimit="num|Infinite"
   memoryLimit="percent"
   webGarden="true|false"
   cpuMask="num"
   userName="{username}"
   password="{secure password}"
   logLevel="All|None|Errors"
   clientConnectedCheck="hrs:mins:secs|Infinite"
   comAuthenticationLevel="Default|None|Connect|Call| 
               Pkt|PktIntegrity|PktPrivacy"
   comImpersonationLevel="Default|Anonymous|Identify|
               Impersonate|Delegate"
   responseDeadlockInterval="hrs:mins:secs|Infinite"
   responseRestartDeadlockInterval="hrs:mins:secs|Infinite"
   autoConfig="true|false"
   maxWorkerThreads="num"
   maxIoThreads="num"
   minWorkerThreads="num"
   minIoThreads="num"
   serverErrorMessageFile="" 
   pingFrequency="Infinite" 
   pingTimeout="Infinite" 
   maxAppDomains="2000"
/>

Machine.config 始终是继承的。

来自MSDN :

Multiple configuration files, all named Web.config, can appear in multiple directories on an ASP.NET Web application server. Each Web.config file applies configuration settings to its own directory and all child directories below it. Configuration files in child directories can supply configuration information in addition to that inherited from parent directories, and the child directory configuration settings can override or modify settings defined in parent directories. The root configuration file named systemroot\Microsoft.NET\Framework\versionNumber\CONFIG\Machine.config provides ASP.NET configuration settings for the entire Web server.
