Running Lisp in Production (2015)

The flight search was designed 20 years ago with the goal to disrupt mainframe-based flight search systems domain:

Here is some background on that particular application:

How would you know that?

The claim was that something which would take weeks in say Python would take minutes in Lisp. Then this flight search system is presented as evidence.

I just don't see how it is any form of evidence for that rather extraordinary claim? It just shows it is possible to write complex software in Lisp, but I wasn't disputing that. I'm disputing the claim of 100 x productivity.

I was addressing your 'That is just an algorithm, isn't it?', in case you would be interested what that application is actually about.

There was no general claim of 100x productivity. The commenter wrote: "I had a lisp master that did teach me that what had taken me weeks in c, c++ and python code he could do it in lisp in minutes"

That was his personal impression, not a general claim. I can't also imagine how this could be a general claim.
