Hi Kristin,

Ensure that you are using the latest version of Sahi Pro, as performance-related issues are often addressed in newer releases.

1. Enable Sahi Auto Threading

   Ensure that the Auto Threading feature is enabled in userdata.properties:

   • sahi.auto_thread.enabled=true

   • Set sahi.threshold.cpu_usage to a value between 70 and 90.

     The optimal value may vary depending on the system configuration, so it is recommended to run the scripts multiple times to determine the best value for your environment.

2. System Resource Availability

   Playback may slow down if other applications are consuming significant RAM or CPU resources.

   Please ensure that sufficient system resources are available for the automation runs.

3. Disable Browser Background Tab Throttling

   Chromium-based browsers such as Google Chrome and Microsoft Edge use Background Tab Throttling for power optimization.

   This can slow down automation running in background tabs.

   To disable this feature:

   • Open browser_types.xml

   • Add the following option to the browser startup parameters:

   --disable-background-timer-throttling
   

   Example configuration:

   <options>--no-default-browser-check --user-data-dir=$userDir\browser\chrome\profiles\sahi$threadNo --proxy-server=127.0.0.1:$port --disable-popup-blocking --always-authorize-plugins --allow-outdated-plugins --enable-npapi --incognito --disable-background-networking --disable-component-update --disable-renderer-backgrounding --disable-backgrounding-occluded-windows --disable-background-timer-throttling</options>
   

4. AWS Instance Configuration

   If the execution is running on Amazon Web Services instances, it is recommended to enable Unlimited Mode:

   • Log in to AWS Management Console

   • Right-click the instance used as the Sahi node

   • Go to Instance Settings → Change Credit Specification

   • Enable Unlimited Mode
