How GoogleChrome handle multiple tabs without decreasing the performance ?

I have a react application with multiple tabs, in each tab we can add one or multiple highcharts. Once we reach the third tab, the application becomes very slow, took more than 15 seconds to do actions like adding new tab, delete tab, adding or removing highcharts. I'm already using functions of optimisation like memo, useMemo, useCallback, ... So I'm wondering if there is a possibility to unmount or kill the already visited tabs without hiding them in order to save the memory for the active tab. If you have any idea of how I can modify the architecture in order to speed up the application, because, I'm wondering how google chrome for example handle multiple tabs without decreasing the performance.
