I compiled fpc from the sources from the svn repository today, but
the results are almost the same as I posted yesterday (I marked with

Test1:

fpc (FastMM4): 2.9 sec - factor = 1.30
delphi (standard MM): 3.1 sec - factor = 1.34

Strange, for me most tests improved by at least 10 %. Did you use a
recompiled rtl compiled with -O3p3r?
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.
