It may be interesting if you can give the same information for other chess
programs.
I have no idea what movei likes because I never planned it for special
processors.
You can try the public movei in order to see how many nodes per second it
searches in the opening position.
Public Movei does not support analysis(next public movei will) but it supports
Fen and you can start with time control of 10 hours per game and ask it to play
in the opening position in order to find out the number of nodes based on the
winboard debug file.
