For the moment you might try the sed that comes with the package from 
unxutils.sourceforge.net. This doesn't depend on cygwin and might be faster. 
But I admit that for so huge comparisons it would be best to do a built-in 
regexp-analysis, because this would avoid the creation of temporary files 
alltogether. Perhaps you could create a RAM-disk for your temporary files and 
sed.exe.

Try menu "Directory"->"Run Operation for Current Item" (F6).
