Thanks Joaquín. That fixes all. I'd noticed a bit in the doc about > initialisation - just my attempt to write a minimal test case got the better of me.

It's not your fault at all, the problem is subtle and I definitely need to document it thoroughly.

Release is still slower than debug under MS - 60 cf 56s with my computer cranked up to full tilt.. Put that down to some dubious MS code generation.For comparison the example program took 927s for hashed factory when compiled as debug and 1365s when compiled as release (ok I didn't repeat the tests!) I'll have to get a smaller test file :-)

I don't really know why you're observing such erratic behavior. I've done the tests myself here with what I believe is the same text file as yours (http://www2.cddc.vt.edu/gutenberg/ etext92/bible12.txt ) and my results are: debug string : 5.09 s release string : 1.33 s debug flyweight : 18.59 s release flyweight : 1.97 s Environment: Intel Core2 CPU T550 @ 1.66GHz 1.00 GB RAM Windows XP Media Center Edition 2002 SP2 MSVC++ 2005 Express Edition If you have any clue why your results differ so much please share it with me.
