I've just set this up on my laptop (Celeron 1.3Ghz, 128M ram), and I've got to take the string up to 32 Meg before I start seeing any appreciable effect.
Using the simple expedient of print time, "\n"; for the timer statements, it does confirm that the return is usually starting and finishing within the same second (there's the occasional second discrepancy).
Possible suggestions:
- The string is far bigger than you expect
- You're running out of memory
- Your timing code is off
- You're counting the returns across the lifetime of the process, and it's happening more than once
- You could use references instead (which avoids having to clone the string), although this sidesteps the question of why it's misbehaving
