Hi, I'm having problems with my domain because sometimes this app becomes very slow to respond, I've to restart it to fix it. it is happening every day.

I checked under the "Diagnose and solve problems >> Availability and Performance" section, here shows CPU usage of less than 80% and memory usage of less than 500MB.

Also, I've set up auto-healing, and it's working fine. But can't really find what and where is the problem.

So, what should we do to find out exactly where the problem is and why our web application is slowing down?

    Hi Developer,

    I think Always on feature in your app service is not turned on. Websites unload if they sit idle for too long, which helps the system conserve resources.

    Always On (available for Standard tier websites) keeps the app loaded even when there's no traffic. If you are not using Standard tier, it's turned off by default. So please check it.

    Thanks for reaching here! When you browse the app and pages load slowly and sometimes timeout. This can be caused by application level issues, such as:

    • network requests taking a long time
    • application code or database queries being inefficient
    • application using high memory/CPU
    • application crashing due to an exception

    You may follow below troubleshooting steps in sequential order to narrow down the issue:

    1. Observe and monitor application behavior
    2. Collect data
    3. Mitigate the issue

    Please let us know if further query or issue remains.
