Has anyone else noticed zunzun slowing down considerably over time? I used to be able to pump out curve fits in minutes, now I watch on as I see:

"Currently using 1 process (the server is busy)".

What used to to take minutes now takes hours sometimes. Is there anywhere else on the net that has the same functionality as zunzun? Or is there any easy to use curve fit programs out there?

What type of curve fitting are you trying to do? Logit? OLS?

How many variables are you fitting?
