This was a long time ago and it is easier to make an improvement when the level is weaker. I did not follow improvement in computer chess not in the last 10 year but I do not remember big improvement like the improvement in the last year when you compare programs on the hardware that people use. Note that most people do not use 2 processors so it is logical to make comparison of performance on the hardware that is used. Uri
