AMD Ryzen 7 5800X 8-Core Processor, timer & PROCESSOR-CLOCK of 4192MHz
Peak WorkingSetSize         = 13982 MB
Current WorkingSetSize      = 67 MB
Total memory size           = 31 GB
Available memory size       = 17 GB
Total paged memory size     = 40 GB
Available paged memory size = 16 GB

I now use ...
SetProcessWorkingSetSizeEx(
 hProcess,
 1000000000,	/* dwMinimumWorkingSetSize 1GB */
 16000000000,	/* dwMaximumWorkingSetSize 16GB */
 QUOTA_LIMITS_HARDWS_MAX_DISABLE /* Flags */
);

This minimizes the time for a/the first (large)
allocation and discourages the OS to swap out
deallocated memory.
