Comment (by simonpj):

 What does "no optimisation" and "threshold 100" mean?  I though if
 "threshold 100" means that if a literal is > 100 bytes then it is put in
 the extra file, then every single line will do that, so the threshold is
 irrelevant.

 I wonder why it every slows down?  Just the extra file handling?
