At least this is certainly true for FPC on Windows case.
Do you remember the factor 10 compiling speed advangage of Delphi7 compared
with FPC 2.4?

I do. I also remember that one of the goals of DoDi's previous set of
refactorings
was to address that discrepancy.
Really? I didn't see any benchmarks?
And since they were rejected, FPC will continue to be slower than Delphi.
Cum hoc ergo propter hoc.
This is a typical showcase for the premature micro-optimization --
for a few percentages of speed in the short term,
you pay in reduced code maintainability,
which precludes high-level optimizations in the long term.
A very small group of unpaid people maintaining a compiler over several
architectures and operating systems? Seems like the fpc team is doing
quite well.
