You can test on t at h server how much faster is copying one big file
than hounders of small files.
My tests shows that copying 100 tilesets (700kB, 138 actuall tiles)
over nfs on LAN needs 8 seconds for 1 file per tileset and 65 seconds
for one file per tile.

Don't forget about blank tiles. Serving tiles with zoom bigger than
z12 requires no mysql access, blankness info is saved in tileset file.
