![]() ![]() On the other hand, Safari's memory usage was stable at 80MB. The black dots in the graph indicate the timing of work, from the left 'when you enter the URL of Twitter' 'when Twitter is displayed for the first time' 'when you get the feed' 'when you open the second tab' 'When you load Gmail from your favorites' 'When Gmail is first displayed' 'When you open your inbox' 'When you view the newsletter' 'When you close Chrome', and finally Chrome's memory usage has exceeded 1GB. Changes in CPU usage are also shown in dark waveforms. With 2 tabs open, if you graph the memory usage (vertical axis) and time (horizontal axis) of Chrome, it looks like this. You can see that Safari uses 73MB and Flotato uses 63MB, while Chrome uses 730MB, which is about 10 times as much memory. First, below is a bar graph showing the average memory usage when using Twitter in one tab. ![]() ![]() I opened Twitter and Gmail in Chrome and Safari in separate tabs. Then, I built a macOS Big Sur environment in a virtual machine and conducted a comparative experiment with the newly installed Chrome / Safari while taking snapshots of the usage status at 4 millisecond intervals with psrecord. Just prepares MacBook Pro (16 inches) with built-in Intel Core i9 (2.4GHz), DDR4 32GB, AMD Radeon Pro 5500M. Morton Just, who develops the browser ' Flotato ' for macOS, reports the result of comparing the memory usage between Chrome and Safari.Ĭhrome RAM / CPU usage vs. 20:00:00 Experimental result that 'Chrome consumes 10 times more memory than Safari on macOS' ![]()
