Because the gap is so big I think not substantial.
Given that (please correct me if I am wrong):

- FPC bottleneck is disk IO and not compiler logic and calculation.
- Delphi is much faster than FPC.

-> Delphi uses a file access approach which performs much better than the 
approach of FPC.

or it isn't true that FPC bottleneck is disk IO. Are we absolutely sure about 
the bottleneck?
