I also speculate if its actually any faster, since I need to change

writes. However, I think for what you're doing you may be better off
reading the file into normal memory and manipulating it there. Even with
copy on write, you're essentially forcing the OS (through a write
protected memory exception) to copy the file into memory anyway.
Ok. Thanks! That's what I'm doing now.
