I have now measured the speed of 2.04 vs 2.03 on English on the unlv bus.3B set. On my machine running 2.03 compiled fresh with the current compiler, and 2.04 also compiled fresh on the current compiler, both with the 2.02 data files, I had identical accuracy and 2.03 ran in 7m30s vs 7m22s for 2.04. Can you(Adam or Remi) supply an image on which it runs slower? I would like to draw a line under 2.04 if possible this week, so I can start on 3.00. Ray.
