### AspProcessorThreadMax

This metabase property specifies the maximum number of worker threads per processor that IIS will create.

Note This setting can dramatically influence the scalability of your Web applications, and the performance of your server in general. Since this property defines the maximum number of ASP requests that can execute simultaneously, this setting should remain at the default unless your ASP applications are making long-running calls to external components. In this case, you may increase the value of AspProcessorThreadMax. Doing so will allow the server to create more threads to handle more concurrent requests.

If this metabase property is changed, the Web server instance must be stopped and restarted in order for the change to take effect. The Web service setting for this property is applicable to all in-process and pooled out-of-process application nodes, at all levels. Metabase settings at the Web server level or lower will be ignored for in-process and pooled out-of-process applications. However, settings at the Web server level or lower will be used if that node is an isolated out-of-process application.
