Pretty fast string class

I wrote my own string class, that is 5X faster than std::string for creation and 2X faster for copying. However, it is slower if I create a string that was previously deleted. I’m not sure what they are doing, but in that case creation is 2X faster than mine.

It would be really cool if I could get it faster in all cases.

Here’s the code:
RakString.cpp
RakString.h

Times are in milliseconds
Ref is just inserting a number, to show the speed of the list itself.
Rak is my string
Std is the std::string

Insertion 1 Ref=0 Rak=25, Std=102
RemoveHead Ref=106 Rak=4964, Std=8577
Insertion 2 Ref=1 Rak=22, Std=12
RemoveTail Ref=0 Rak=0, Std=0

Insertion 1 Ref=1 Rak=24, Std=102
RemoveHead Ref=107 Rak=4868, Std=8585
Insertion 2 Ref=0 Rak=23, Std=13
RemoveTail Ref=0 Rak=0, Std=0

Insertion 1 Ref=1 Rak=25, Std=104
RemoveHead Ref=107 Rak=4879, Std=8553
Insertion 2 Ref=0 Rak=22, Std=13
RemoveTail Ref=0 Rak=0, Std=0
