Why The Web Page Takes Eternity To Load

If the computer is slow due its age, Tecrep24 computer repair services can make a quick fix on-site. If the website is slow, the culprit is third party advertisement and analytics scripts. Many users have already accepted this conclusion but the truth is 100 most common bits of JavaScript eat up about 59% of the execution time of scripts.

Third party scripts only represent one factor when calculating total web page load time. Other factors include network latency, bandwidth, file sizes and processing power. However, the time to execute JavaScript code will have a significant effect on loading time.

There are different types of user-perceived delays. One is visual delay or when nothing shows up because it is obviously loading slowly. Visual delay is dominated by network latency and large resource payloads but large script files also contribute to the delay.

Delays can impact on interactivity. For example, when a user tries to click on an icon and nothing happens immediately, the delay is the result of JavaScript execution. Google scripts impose more delays than anyone else’s. The two biggest reasons for delays include Google’s Double Click Ads that adds 30 ms on average and Google Tag Manager that adds 386 ms on average.

The two Google scripts that have the most impact are typically found in website code. Google Double Click Ads consume a total of 466, 442 seconds of execution time while Google Tag Manager devours 421,590 seconds during the twice a month data gathering periods. Facebook code accounts for 145, 169 seconds.

In the worst average delay, the winner is Word Ads which is a WordPress ad system that consumes 2543 ms every time that it loads. Web users who have recognized that third party scripts are the reasons for their troubles have installed content or ad blocking extensions in their browsers. They also block third party requests on a network level.
