Because Chrome is a very memory-intensive browser, computers that use slow processors and don’t have access to enough memory often experience sluggishness when running it.

When Chrome is initially installed, it creates and enables multiple plugins, most of which a regular user doesn’t need. By typing in “about:plugins” in the address bar and pressing Enter, a user can disable the unnecessary plugins, which should improve the performance. Leave Flash, Java and Silverlight plugins enabled if the user watches YouTube or Netflix content.

Extensions affect the performance in the same way plugins do. They can be disabled or entirely removed by accessing the Extensions settings option in the main Settings window. By pressing Shift and Escape at the same time, a person can analyze how much memory each extension is using, and disable them accordingly.

When the cache becomes too big after not being cleared for a long time, it slows down the browsing process because the program reads certain content from the hard drive instead of getting it directly from the Internet. Having a hard drive with low RPM and a slow processor exacerbates the situation further. By clearing the data from the cache and history, a user can temporarily improve the performance.
