Both Delphi 7 and Kylix 3 compiled MSEide feel more snappy than their FPC

Some more tests, starting MSEide, loading and highlighting the 277441 lines
MacOSAll.pas from FPC 2.4.0:
FPC 2.6.2 Windows 3.2..3.5s
Delphi 7 Windows 4.0s
FPC 2.6.2 Linux 5.0s
Kylix 3 Linux 4.0s.
It seems there is actually a benefit of the reference counted Free Pascal
UnicodeStrings on Windows.
Any idea, why FPC Linux is slower than FPC Windows?
Loading and highlighting does not sound like a task where many OS calls
are involved.
Codepage conversions, most likely: Martin uses UTF-16 everywhere.
On Windows, FPC uses the native support for UTF-16.
Not exactly sure what happens on Linux.
Another source of slow-down may be file search: Windows ignores case.
Linux does not -> depending on what you do, you need to search 3 times more files.
