 ## How do I troubleshoot a high CPU-consumption scenario?
 
 In some high CPU-consumption scenarios, your app might truly require more computing resources. In that case, consider scaling to a higher service tier so the application gets all the resources it needs. Other times, high CPU consumption might be caused by a bad loop or by a coding practice. Getting insight into what's triggering increased CPU consumption is a two-part process. First, create a process dump, and then analyze the process dump. For more information, see [Capture and analyze a dump file for high CPU consumption for Web Apps](/archive/blogs/asiatech/how-to-capture-dump-when-intermittent-high-cpu-happens-on-azure-web-app).

-## How do I decrease the response time for the first request after idle time?
-
-By default, web apps are unloaded if they're idle for a set period of time. This way, the system can conserve resources. The downside is that the response to the first request after the web app is unloaded is longer, to allow the web app to load and start serving responses. In Basic and Standard service plans, you can turn on the **Always On** setting to keep the app always loaded. This eliminates longer load times after the app is idle. To change the **Always On** setting:
-
-1. In the Azure portal, go to your web app.
-2. Select **Configuration**
-3. Select **General settings**.
-4. For **Always On**, select **On**.
