Why does IE11 display a "Total Memory" value much higher than the heap snapshot size?

Why does Internet Explorer 11 display a "Total Memory" value that is significantly higher than the heap snapshot size, and what factors contribute to this discrepancy?

Internet Explorer 11 (IE11) displaying a "Total Memory" value much higher than the heap snapshot size is often due to non-heap memory usage. Here are some factors contributing to this discrepancy:

Non-Heap Memory: IE11 includes non-heap memory in the "Total Memory" value, which encompasses things like the browser's own code, JavaScript engine, and other system resources. This is separate from the heap memory used by your application1.

Memory Leaks: Continuous memory leaks in your application or the browser itself can cause the total memory usage to increase over time, even if the heap size remains relatively stable.

Browser Caching: IE11 may cache resources, which can increase the total memory usage without significantly affecting the heap size.

Garbage Collection: The browser's garbage collection process might not immediately release memory back to the system, leading to higher total memory usage.

To address this issue, you can:

Profile Memory Usage: Use memory profiling tools to identify and fix any memory leaks in your application.

Optimize Resource Usage: Ensure efficient use of resources and minimize unnecessary memory allocations.

Update Browser: Ensure that you are using the latest version of IE11, as updates may include fixes for memory management issues.
