Memory Pre-Allocation Trick?
I have a VFP7 class with an empty string property. After instantiation, from 3 to 9 methods get called, and each concatenates 100-500 bytes in rapid succession, resulting in about a 5k stirng property when it's done. The caller consumes this string property before destroying the object.
Would it make sense to pre-allocate memory for the object by setting the string property to Space(8192), and on the first write set the property to the first string and then concatenate after that?
I am thinking that the object would run "faster" because the OS (or runtime) would not have to grow the stack space for the object as it runs. This is for a web app where I have potentially 60-70 objects going at any given second.
Thanks.
