Although Google wants websites to be as lightweight and fast as possible, there comes a time when this is almost impossible. Webpages are getting larger and heavier, working with huge databases, which can cause some websites to load slower than usual. Additionally, webpages increasingly show more images, multimedia content and front-end content that is run directly on the user’s computer, like scripts. When such content is run and saved on the computer’s memory, the entire computer starts to work very slowly, especially if we have a low-end processor or little RAM memory.
After analyzing the consumption of a browser like Google Chrome, we can divide it into 3 sections: the resources consumed by the browser and all the essential components needed to function; all the installed extensions that are loaded individually on the memory; and all the webpages opened at the same time in the browser window.
Given that each element is loaded as a different process within the browser, it is really easy to know which element consumes most of our computer’s resources, causing it to perform poorly. If we use Windows Task Manager, we can see all the browser’s processes, although we will not be able to identify the source of the problem.
Luckily, Google Chrome has a task manager (it probably is the only feature that Firefox and other browsers lack) that allows us to see in detail the consumption of each of the browser’s elements so we can identify them.
To open Google Chrome’s task manager, we just have to press the “Shift + Escape” keyboard shortcut to see a simple window like the one below.
As we can see, every website and extension currently open on the browser will be displayed here. On the upper side of the window, we can see different columns that we can sort from high to low (or vice versa) by clicking on them.
If we click on the CPU column, we will see first the websites with the highest processor usage. If we click on the Memory column, we will see the websites with the highest RAM consumption.
If there is a webpage with a very high memory or CPU usage, we can click on in on the task manager and then click on the “End process” button, which will immediately close the webpage, or extension, that is causing performance problems.
Of course, we can also use this feature to identify any webpage that may be using our computer to mine cryptocurrencies by spotting any excessive increase in CPU usage.
