Hi,
I have changed the FastMM4 that it seemd to work with fpc now. Here are
the results of my prior tests now with FastMM4 for fpc:
Test1:
fpc (standard MM): 3.1 sec - factor = 1.34
fpc (FastMM4): 3.0 sec - factor = 1.30
delphi (standard MM): 3.1 sec - factor = 1.34
delphi (FastMM4): 2.3 sec - factor = 1
Test2:
fpc (standard MM): 2.8 sec - factor = 1.47 fpc (FastMM4): 2.2 sec
- factor = 1.15
delphi (standard MM): 2.9 sec - factor = 1.52
delphi (FastMM4): 1.9 sec - factor = 1
Test3:
fpc (standard MM): 2.5 sec - factor = 1,19
fpc (FastMM4): 2.1 sec - factor = 1
delphi (standard MM): 3.4 sec - factor = 1.61
delphi (FastMM4): 2.1 sec - factor = 1
As you can see the benefits are not as big as compared to the standard
Delphi MM, but it is still slightly better than the standard MM in fpc
(and it reports memory leeks). I have not yet tested all of its features
but it seems to work so far.
I've commited another bunch of small optimizations, maybe you can
retest. FastMM is implemented in assembler and hand optimized so it's
clear that it's rather fast.
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 **
where the results have changed):
Test1:
** fpc (standard MM): 3.0 sec - factor = 1.30
fpc (FastMM4): 2.9 sec - factor = 1.30
delphi (standard MM): 3.1 sec - factor = 1.34
delphi (FastMM4): 2.3 sec - factor = 1
Test2:
fpc (standard MM): 2.8 sec - factor = 1.47
** fpc (FastMM4): 2.1 sec - factor = 1.10
delphi (standard MM): 2.9 sec - factor = 1.52
delphi (FastMM4): 1.9 sec - factor = 1
Test3:
fpc (standard MM): 2.5 sec - factor = 1,19
fpc (FastMM4): 2.1 sec - factor = 1
delphi (standard MM): 3.4 sec - factor = 1.61
delphi (FastMM4): 2.1 sec - factor = 1
