Indexing should add file location and file size total to database rather than processing every file requiring an enormous amount of I/O bandwidth causing a sluggish indexing process. Also, do not start indexing other folders until the current folder is completely indexed. As I have noticed in 1.1.27 that when reindexing, the folder would not completely index, and move on to others, then start downloading files from other systems to retrieve the non-indexed files, although the files already exist on the current system and does not need to be re-downloaded.
