Component vendors are interested in selling components.

The honest loyality of component vendors to 
Borland/CodeGear/DevCo/Embarcadero is next to non-existant. The reason 
Delphi is the focus
is that they invested into that, and that Embarcadero is using
anti-competitive tactics.

I've been a Borland Technology Partner. Besides my personal experience,
I sure know how component vendors are treated.

Supporting FPC just has be to be attractive enough so that the
component vendors are willing to take the risk of not getting
any more "love" from Embarcadero.

Removing technical obstacles therefore helps. Language compatibility
is something that helps a lot.

 From our measures the Delphi and Kylix compilers in most cases
on x86 produces code that is about in the order of 50% faster than FPC. 
So probably there is some issue specific to your test suite that is 
triggering this huge difference, it should not be that big. For some
applications (like ours), still the difference is too big, so we only
use FPC on platforms where there is no compiler from Embarcadero, and
keep all of our source code compatible to Delphi 7 + Kylix + FPC. 
Language compatibility enables us to have a choice. Without this choice,
we would have needed to move to a different programming language.
Choice is good, competition is good, compatibility amongst competitors
is good.
