That's a long time by any standards.
I assume its processing an enormous amount of data?

How much slower?

There are all sorts of possibilities but without any idea of what it 
does or how it does it we would only be making wild guesses.

Here are some...
Maybe you have increased your data size since last time? Maybe the 
computer configuration has changed? Maybe somebody modified the
script? Maybe the data got moved to a network drive, or an
optical disk? Who knows?

Without more detail we really can't say.
