These numbers tell you exactly nothing. At best they give
you an indication of how complex your project is.

I have Delphi compile times of over 2 minutes on projects
that have maybe 5.000 lines. It takes this long, because
there are a lot of dependencies on external packages and
whatnot, and Delphi takes a long time loading the packages
and correctly resolving the symbols.

Just for fun, I once managed to have delphi compiling 5 minutes 
(!) on a single form project. (granted, I did put up some messy
dependencies :))

The only way to measure the compiler speed is to create
1 very large unit (say 500.000 lines) and let the compilers
compile that single unit.
