I'm not sure I understand what you're seeing: if your repository is already set up with core.filemode set to false, Git won't check the executable flag on the files. What leads you to think the speed slow-down is related to checking whether the file is executable? If setting cygexec makes a noticable speed difference even with core.filemode false, I can only conclude the problem is somewhere below Git and related to how the Cygwin DLL provides file access. FWIW, having just checked the Cygwin user guide's fstab instructions[0], the noacl setting should be ignored on NFS filesystems; if you're seeing that make a difference, that looks like a bug.
