Full Text Indexing in Ruby is Faster than Java

Jim Wiseman John Wiseman, who is porting Ferret to Lisp, reports on the blazing performance of Ferret.

(Ferret was originally a port of Lucene, but recent alteration to the file format has increased performence 5x over GCJ, and then the author ported to C to get an order of magnitude improvement.)

The moral of the story is not one of premature optimization, but working with pliable languages vs working with brittle ones.
