Does running Whatfix content impact my application performance?

Whatfix has a negligible impact on the performance of any web application. The following are the two factors that generally impact performance:

• Size of JavaScript: The Whatfix JavaScript file size is only 700KB (compressed). The browser caches this file and ensures that the user downloads them only once (first access). 
  
  
• Execution time of Javascript: Considering all Whatfix widgets are enabled, the Whatfix JavaScript execution during page load takes approximately 400 milliseconds. However, depending on the extent of advanced capabilities and configurations in your account, the execution time may increase.

Browsers usually load and execute JavaScript in the background, only when the page is almost completely loaded.

Hence, Whatfix has minimal to no impact on performance of your application.
