Program runs more slowly with Memory Debugging enabled

The Memory Debugging library performs more checks than the memory allocation routines of normal runtime. However, these checks make the library slower.

Solution

If your program runs too slowly when Memory Debugging is enabled, there are several options you can change to speed it up.

Try reducing the Heap Debugging option to a lower setting. For example, if it is currently on High, try changing it to Medium or Low.
Increase the heap check interval from the default of 100 to a higher value. The heap check interval controls how many allocations might occur between full checks of the heap, which can take some time.
A higher setting (1000 or above) is recommended if your program allocates and deallocates memory very frequently, for example from inside a computation loop.
You can disable the Store backtraces for memory allocations option, at the expense of losing backtraces in the View Pointer Details and Current Memory Usage windows.
