Slower for what? Some example code that demonstrates the problem(s) would be
appropriate. If it's specifically related to file I/O, this is a well-known
problem that (I think) has been corrected for the Ruby 1.7 code.

Please check the newsgroup or mailing list archives; this has been discussed
to death over the last few weeks. Some of the subject lines for related
threads include:

    "file reading impossibly slow?"
    "Why is Ruby so slow?"
    "Development of Windows Version of Ruby"

There are also a few (older) pages discussing this on the RubyGarden Wiki,
e.g.

    http://www.rubygarden.org/ruby?WindowsSupport

The Cygwin version of Ruby isn't "going away", although the Pragmatic
Programmers' Ruby installer for Windows has indeed moved to a mswin32-based
build instead of a Cygwin-based build. There is nothing that prevents you
from building a Cygwin version of Ruby from the source code for yourself.

Hope this helps,
