Just got 4.0 today. Running on a 450 MHz P2 under W98. Observations: Interface is nice, but not a lot different. Graphics (2D and 3D) come up noticeably faster The bad news is that number crunching appears to be slower. I have an application in which I take a potential function which is a function of R and theta and expand it in terms of Legendre polynomials. To do this I do a 2D curve fit on the data and then use NIntegrate to get the Legendre coefficients as a function of R. Here is the timing for two different applications.
