Hey Jacopo. It looks as though the improvement in performance is due mainly to a logging parameter change. However, the original post indicated a 4x performance deficit, which isn't really reflected in the below statistics.
It's faster, but nowhere near 4x. Is it possible to downgrade freemarker to gain back performance?
