Large Collection (280,000 Tracks) Slow search

Anyone have any suggestions on what file structure works best? I have Roon searching my various artist compilations (71,287 tracks) separately from the named artist tracks (214,342 tracks). The various artist compilations are organized by album name and, if multiple disk, by disk number. The named artists are organized first by artist name and under that the album name and disk number (for multi-disk sets).
