[This is part of the Wide Finder 2 series.] I’ve just updated the Wide Finder wiki with a straw-man benchmark (see “Strawman”), with sample Ruby code and output. Argh... it takes Ruby over 23 seconds to process just 100K lines. I hear talk of a Solaris/SPARC optimized version, gotta track that down. Comments please on the benchmark, then we can all start bashing our heads against the big file.
