FileObject fileset excesively converts added links back and forth to detect whether they are broken or not. This affects performance of e.g. compilation of java files, but also their visualization, because the isUpToDate method delegates to compiler. Also some caching in FileObject filesets could speed up accessing their contents. In general any call to FileUtil.fromFile seems to be expensive. (see also issue #33999)
