We’ve looked at how Web components like CSS, HTML, and JavaScript can affect a website’s performance. Today we’ll talk about how third-party issues can also have a negative effect on performance. Read on for tips on predicting, monitoring, and ultimately avoiding these issues.

 

How Third Party Content Affects Website Performance

Website plugins: If there are embedded Flash movies, audio, or video in your Web application, they sometimes won’t run correctly without JavaScript.

Content view: Some webpages use Java applets for interactive content like online games. If the Java plug-in isn’t installed, then the browser won’t be able to run the applet and interactive content can’t load.

Ads: Live ads in a web page that pull data from a third party site will cause performance issues in websites.

Live content: Live third-party content like, game scores or a stock ticker, will constantly refresh the page with the latest updates. This can affect other page elements and slow their load times.

 

How to Monitor for Issues with Third Party Content

  • Record your Web transaction: This will establish how well your applications are performing. You can then compare this to your baseline and identify which page element is causing the issue.

  • Track page load time: Establish a baseline for how long it should ideally take Java or Flash applications to load. Then monitor the load time for each step in the page. If a page loads slowly, or fails to load, you’ll receive an alert about the problem in the page.

  • Use image matching: You can measure how long it takes for third-party content to load using image matching. This will tell you if they’ve loaded within the specified time. Then you know if the transaction passed or failed.
  • Monitor JavaScript: You can monitor JavaScript in order for applications like Flash or other embedded videos to run without any issues.
