Studio is VERY slow

I've been having some major issues with the performance of Studio in my sub-prod development instance (not PDI), and I'm not sure what would cause this since Studio worked as expected for years, and then about 6-7 months ago I started to notice the issues.

 

The biggest problem I've been having is that when loading an app to work on, sometimes it will take 1-2 minutes to load, and in the case of one specific custom scoped app it can take 3-5 minutes to load initially.

 

Another issue is that if Studio is open in the same browser, regardless of which tab it's on and a file related to the scoped app is created, updated or deleted, all the tabs with that instance open basically freeze for 2-3 minutes and can't be used until the latest version of the file shows up in Studio.

 

Has anyone else seen issues like this or know what could possibly cause such poor performance?

Hi @MHager ,

Here are some steps you can take to diagnose and potentially resolve the issue:

  1. Clear Browser Cache and Cookies:

    • Sometimes, accumulated cache and cookies can slow down performance.
    • Clear your browser's cache and cookies, then restart the browser.

  2. Use a Different Browser:

    • Try using a different browser to see if the issue persists.
    • Ensure that the browser you're using is up-to-date.

  3. Browser Extensions:

    • Disable any browser extensions that might interfere with the loading of ServiceNow Studio.

  4. Check Network Connectivity:

    • Ensure your network connection is stable and has sufficient bandwidth.
    • Check for network issues that might be causing delays in loading Studio.

  5. Instance Performance:

    • Monitor the performance of your sub-production instance.
    • Use the System Diagnostics tools (e.g., node logs, slow queries) to identify any performance bottlenecks.

  6. Application Size and Complexity:

    • Large custom scoped applications can take longer to load.
    • Review the application to see if there are any large scripts or numerous records that might be causing the delay.

  7. Check for Unnecessary Files:

    • Clean up any unnecessary files or old versions within the scoped application.
    • Review and remove unused code, UI Pages, or other resources.

  8. ServiceNow Versions and Patches:

    • Ensure your instance is running the latest version or patch of ServiceNow.
    • Sometimes, performance issues can be resolved by updating to the latest version.

  9. Browser Developer Tools:

    • Use the browser’s developer tools to monitor network activity and identify what is taking time to load.
    • Look for any errors or slow-loading resources.

  10. System Logs:

    • Check the system logs for any errors or warnings that might give you a clue about the performance issues.
    • Look for any patterns or recurring issues.

  11. ServiceNow Performance Analytics:

    • Use Performance Analytics to monitor and analyze the performance of your instance.
    • Identify any trends or spikes in resource usage.

Additional Tips:

  • Load Balancing:

    • If your instance is load-balanced, check if the issue is specific to a particular node.
    • Sometimes, issues can be node-specific due to resource constraints or configuration.

  • Scheduled Jobs:

    • Review any scheduled jobs that might be running at the same time you're experiencing slowness.
    • High-resource jobs can impact overall performance.

Thanks,

Ratnakar
