As I don't speak gdalese, what size do tiles have in your test? It's my opinion ideally efficient tiles over a broad range of compression modes, that fit workflow on today's machines best, are in the order of about 1 to 3 megabyte, not the legacy 8 kilobyte (uncompressed, of course). I believe that for some compression modes, tile size does have a considerable impact on efficienty.
