Nested STL vector using way too much memory

Question

I have an STL vector My_Partition_Vector of Partition objects, defined as

struct Partition // the event log data structure
{
    in         


        

Answer 1

If you store a near constant amount of objects, then I suggest to use a 2-dimensional array.

The most likely reason for the memory consumption is debug data. STL implementations usually store A LOT of debug data. Never profile an application with debug flags on.
