I did some profiling of a very similar program, results posted at
http://blade.nagaokaut.ac.jp/cgi-bin/vframe.rb?key=-pg&cginame=namazu.rb&submit=Search&dbname=ruby-talk&max=50&whence=0

Conclusion: I can see no obvious bottlenecks. When you drill down and work
out how much time is spent in object creation and garbage collection, file
reading and scanning etc. it seems all pretty well balanced to me. The
reading and breaking-into-individual-lines accounts for 1.09 seconds out of
2.53 seconds
