I suspected that but didn't have my Cygwin system handy. The operative 
factor here is that "i386". I have no idea what compiler the Cygwin 
people used to build that Ruby or what optimization flags they used, but 
I do know that i386 is the lowest common denominator. That is 
unfortunately also the case for RHEL, Debian and Ubuntu, and probably 
also the case for Fedora. I think the One-Click installer has more 
optimization.
