Fetching documents means that per document about 2 disk seeks are needed to access the document. For 200 documents, that's not possible in 16ms on a common hard disk, unless everything is chached by the operating system. Your copy operation seems to clear that cache and search times get slower. A solution might be to re-warm the cache after each copy process.
