You are welcome any time!

Did you try Xwin.exe from xc-4-binaries directory?

The speed on GDI and DXWIn32 servers from contrib could
be slow, because both use remote framebuffer, which is a
compromise between speed and stability, i.e to get
MSVC X-servers compiled and stable enough to work.  These
servers do not use anything from XFree86 4.0 code therefore
their performance could not be compared to XFree86 on a Linux

XWin.exe use code from XF86 4.0 and can be compared
to XF86 on Linux.  However, [please note, that most of
the XFree86 extensions do not compile MSVC, therefore
Cygwin Development Tools were chosen.  Cygwin1 UNIX 
emulation layer does affect performance somehow and 
can cause a loss of performance of slower CPU's.

No, You did not do anything wrong.

Well, I could not compare XF between Linux
and Windows at my machine.  I am using
Pentium III 1000 MHZ, with nVidia Geforece2 64 MB
video RAM. Performance loss on my CPU is a matter
of a few seconds, which cannot be noticed.
