Hi Aja,

> It's more than 5000 playouts but less than 20k. Which version

I tried Fuego 1.1(2011, Windows version) on Intel Core i3 540,
 2 cores 4 thread. 3.07GHz.
I played first 4 moves randomly, and next 4 moves are

GamesPlayed    28952, Time           6.8, Games/s        4249.8
GamesPlayed    28750, Time           6.8, Games/s        4249.4
GamesPlayed    42853, Time           9.7, Games/s        4416.4
GamesPlayed    32541, Time           7.5, Games/s        4357.0

Average is 33000 playout/move.

config.txt
-----------------------------------
uct_param_search number_threads 2
uct_param_search lock_free 1
uct_param_player reuse_subtree 1
uct_param_player ponder 0
-----------------------------------
"C:\Program Files\Fuego\fuego.exe" --config config.txt

I did not add "go_param timelimit 10", because 10sec is default.

i7-4702MQ is 4 cores, 8 threads. 2.2 GHz, 3.2 GHz(Turbo Boost)
I'm not sure its speed and whether it used 3.2GHz, but I think
 turbo boost is on when 2 threads.

I summed Fuego's cpu time from their first 10 sgfs.
Total is 2861 moves, cpu time 21443 sec.
21443 / (2861/2) = 15.0 sec / move
It is over 10sec. a bit strange.

Regards,
Hiroshi Yamashita
