This is a very vexed question.

The test of SF team seems to show an increment of 8 Elo with 5 men Syzygy Base.

If you have got a Solid State Driver, you could probably get an higher increment with 6 men, but on my traditional Hard Disk, they highly slowdown the engine, that spends much time in the search of the data base positions rather than in the analysis.
At TCEC Tournament they are working very well on the hardware of Martin Thoresen.

Anyway, a great advantage of using tablebase, is a better evaluation by the engine in some typology of end game.

thanks for the explanation Luigi. But why did they embedded the tablebase to the engine's executable file? so it's stockfish+tablebase in one file right?

Unfortunately TB dimensions are too big for one file.

The Stockfish syzygy versions are only compatible with that format.

For downloading 5 men Syzygy Bases (about 1 GB) you could use one of the following links:

http://olympuschess.com/egtb/sbases/

or

http://chess.cygnitec.com/tablebases/syzygy/

For 6 men there is a torrent:

http://oics.olympuschess.com/tracker/index.php

but downloading the files (150 GB) may take a few days...
