The memory leaks were not the direct reason for the slow down.

LCL program became slower with every repaint. The reason was the
inefficient resource storage in the gtk-interfaces. This have been improved
and there should now be no slow down, even if a LCL program runs several
hours and even if a program leaks handles.

The other speed off effect is the general slowness of the LCL along with
flickering. I think, the main reason for speed off and flickering
components is the missing clipping. We are working on that.

I think, the writelns plays only a minor role. If you see a lot of writelns
then you are testing code in development.
