No, it doesn't need to do that for some readily available data like the file size. But determining whether the file is executable or a symbolic link can cause the file to be opened. Obviously this takes more time than reading meta-data and on a slow file system, the lag will be felt more intensely. If you're only seeing the slow-down with Cygwin facilities and things like 'cd' are very slow too, then it seems like this is something that's at least more acutely felt under Cygwin. why that would be I'm not even going to guess. :-) Perhaps it's time for a full problem report.
