No, the main reduction is not outputting anything to console: from
18.5
sec to 15.9 sec vs. 18.5 sec to 17.5 sec.
I used 'compile-fpc | grep compiled'. Where compile-fpc is a batch
file.
I think it is because you run compilation for the second time and
files were in cache.
Here mu number for the second run without deletion of compiled unit
files (to ensure that source files are cached):
FPC with -O2: 14.7s;
FPC with -O-: 11.4s;
D7: 1.6s.
Results are sad :( It is a good reason to find out why FPC is so slow
even without optimizations. Linking time is less then 1s, so it is not
slow.
