Hmm - well, it was the latest tar file available (3.3.6 I think) ,
on a pentium III (portable), probably running ./gnugo -b 500
or something like that.
I'll run it again at home (I'm at work right now) and mail the result
I got.
*However*, I realised I should have mentioned that the numbers I was posting
today were based on a very old version (3.1.3), since that's what I had
on the machine at work, and there has since been a policy change such
that I can no longer download new code onto a machine at work.
I checked that the influence code was still similar to the latest, but
the speedups are from the old code. Sorry, I should have made that clear.

Hmm - good idea - perhaps for raw micro-optimisation work, there should
be a such a standard timing script. (Unless there already is one - as
usual, I'm very out of touch with latest developments)
I assume there are already scripts to ask gnugo to generate a move at
each position of a game from an sgf file ?
