I also made some tests.

I can confirm tests made by Wayne.
But I am not sure the dynamic link solves the main issue: time to see the Kicad window on screen.
I compiled Kicad using wxMSW 2.8.12 (the last stable version) and wxWidgets 2.9.3 ( the SVN version)
under gcc 4.4 and 4.5.2

With the same compiler version, Kicad binaries, and wxWidgets libs
with 2.8.12 have a size that is roughly half the size of the 2.9.3 version.

On my computer Eeschema is shown on screen about 2 seconds after launching the binary, with 2.8 version.
With 2.9.3 Eeschema is shown on screen about 8 seconds or more after launching the binary, with 2.9 version.

Note when compiled with gcc 4.4, Eeschema (and other kicad applications) is shown on screen faster.

I am afraid this issue could be due to the fact wxWidgets has no more a debug and a release version,
but only an unique version.

If this is the case, this is a bad news.

I also am afraid the use of dynamic libraries add more time to launch Kicad.
It fixes only the size of binaries, that is now a very minor problem.

By the way, the SVN version works fine for me and has fixed annoying issues found in Kicad.
