You are right again ;-) I didn't compile the rtl with the new source...

Now it looks like this:

Test1:
 fpc (standard MM):  3.0 sec - factor = 1.30
 fpc (FastMM4):  2.8 sec - factor = 1.21
 delphi (standard MM): 3.1 sec - factor = 1.34
 delphi (FastMM4): 2.3 sec - factor = 1

Test2:
 fpc (standard MM): 2.1  sec - factor =  1.23  
 fpc (FastMM4):  1.7 sec - factor = 1
 delphi (standard MM): 2.9 sec - factor = 1.70
 delphi (FastMM4): 1.9 sec - factor = 1.11

Test3:
 fpc (standard MM):  2.3 sec - factor = 1,15
 fpc (FastMM4):  2.0 sec - factor = 1
 delphi (standard MM): 3.4 sec - factor = 1.70
 delphi (FastMM4): 2.1 sec - factor = 1.05


Test1 isn't relevant anymore. And in Test2 and Test3 fpc beats delphi 
clearly. The benefits for the FastMM4 are now not that big anymore, but 
it helps to compare delphi and fpc on a fair base, since the impact of 
the MM is now leveled out.
