16gb ram, 开了 outlook, virtual C++, teams, 等等，Chrome 开了 20 页 - 看着不够。

Does chrome browser memory usage include page files?

Yes, Chrome’s reported memory usage generally includes the memory it actively uses, including any that may be paged to disk. Chrome allocates and manages memory as needed, and if physical RAM becomes limited, Windows may page portions of this memory to a paging file on the disk to free up RAM.

When you check memory usage in tools like Task Manager, the total memory usage figure shown includes both in-RAM and paged memory allocations, so Chrome’s memory usage stats effectively cover both types. This includes all components Chrome uses, like extensions, cached content, and each open tab’s processes.

If you’re looking to minimize Chrome’s memory footprint, you might try closing unused tabs, disabling unneeded extensions, or using Task Manager within Chrome (Shift + Esc) to see which processes are consuming the most memory.
