[fpc-pascal] code optimization

[stefan077 at web.de]

Hi all,
 
I am currently trying to get the fastest possible code from fpc on a  modern CPU (Intel Xeon) under Windows XP. I use the compiler options:
 
fpc -Mdelphi -O3 -OpPENTIUMM -Cfsse2 -Cr- -Co- -CO- -Ci- myprogram.dpr
 
Are there any better settings I should use? Compiling exactly the same  program with Delphi7 results in 50% faster code. I understand that fpc  does not support the most recent CPUs, but neither does DELPHI 7. So  what optimizations are done by Delphi 7 that are not done by fpc and why  is this the case?
 
 Stefan
