@Dianne - my assumption was that since all of the fields in the flat file need to be searchable, then a database would be the best approach. I'm wondering how this can be done without a database. Maybe a file for each index - each entry consisting of key-value pairs. For performing a lookup on the index, do some kind of binary search. Is this what you mean?
@skink, @lucky4me - thanks for the optimization tips. I'll try those out. I was kind of assuming that the lion's share of the CPU usage was being done in the DB so I haven't even started on the java-side of the optimization. I'll post some new results soon. @skink - the gzip compression would only be useful for when downloading the data, wouldn't it? After installation/first-time- initialisation, wouldn't all the data be best stored uncompressed?
