The compiler does run faster how-ever when using autotools as a build 
system the number of shell related calls is the main bottle neck and 
over shadows the compiler performance gain. The comment is related to 
your application rather than building RTEMS. We hope you build your 
application more than you need to build RTEMS.

Is this with the MSYS shell or Cygwin shell ? The Wiki documents using 
the Windows cmd prompt and MSYS sh using the installed batch file. You 
cannot have a Cygwin path in the PATH environment variable at the same 
time. This is why the installer makes specific batch files for each target.

What path was this ?

Do you have the Xilinx Cygwin in a global Windows path ?
