Preallocating memory for using programs

Question

Preallocating memory for using programs

In my Windows C ++ program, I allocate several small objects into a bunch (thousands) by calling a new CMyClass ()

It seems that performance is affected because of this.

Is there a way to predefine some minimum memory on the heap for using the program so that the OS starts allocating from this pre-allocated space when ever I call a new CMyClass () to improve performance?

Thank.

It seems you are looking for a memory pool - http://www.codeproject.com/Articles/27487/Why-to-use-memory-pool-and-how-to-implement-it
