Fair enough. But then that raises a more important issue: you are showing Lisp is faster than more popular languages in a way that probably doesn't matter much. When I read the title, I was hoping this isn't some benchmarking or academic exercise, which does not have relevance for real applications. So I was delighted to read that this is something you use in your webapp, only to be disappointed again now.<p>I don't mean to discourage you or be cynical. I love the fact that you are writing interesting articles on the practicalities of using Lisp with actual data behind it. So, keep up the good work. I look forward to more posts.
