IIS 32bit Worker Processes

Top  Previous  Next

One of the performance benefits of the x64 platform is that it increases virtual address space, making more memory available. We recommend that you configure IIS to use 32-bit worker processes when running on 64-bit Windows (Microsoft also recommends this).


Note: If your web app is using the Clarion Database Drivers then you must configure the IIS application pool that you run your Clarion web app under, to use 32-bit worker processes.


An application pool is a group of one or more URLs that are served by a worker process or a set of worker processes. Application pools set boundaries for the applications they contain, which means that any applications that are running outside a given application pool cannot affect the applications in the application pool.





Open IIS Manager.


In the Connections pane, click Application Pools in the tree.


On the Application Pools page, select the application pool that contains the application that you want to change.
