To increase internet speed, users suggest closing unnecessary programs and using the latest web browsers, with Google Chrome being the most favored due to its speed and efficiency. Chrome's "look ahead" feature enhances page loading by pre-downloading resources. While some users prefer Chrome for its performance, concerns about privacy lead others to recommend alternatives like Iron, which offers similar speed without Google's tracking. Regular updates to software and antivirus programs are also emphasized as important for maintaining optimal performance. Users note that while Chrome can be resource-intensive, its perceived speed and user-friendly design make it a popular choice.
