This example uses the memory usage reports that Unity writes to the log when you close the Player or Unity Editor. To create this report, use the -log-memory-performance-stats command line argument. To find your project’s log files, follow the instructions on the log files page.
You can enable or disable the mimalloc allocator in the Memory Settings window. For more information, refer to Native memory allocators reference.
A mimalloc report displays debug statistics about the scene. The following example reserved 1.0 GiB of virtual address space for the heap, of which ~66.3 MiB was committed to use.
