The obvious answer here is yes.  The cygwin1.dll is emulating a POSIX file
system.  The overhead is the emulation processing.  I can say that the
processing is faster than it was a couple of versions back.

If you're concerned for speed of processing the best result is to port it to
native api.  If you are not porting UNIX code, then use the Mingw32 version or
compile with the -no-mingw32 switch.  Search the archives for caveats.
