[Tutor] Memory optimization needed: tarball

[Jonathan Hayward http://JonathansCorner.com]

I have a search engine I'm working on which uses memory inefficiently 
for large data. It indexes to avoid the cost of keeping documents in 
memory, but with a 150M dataset it takes 250M. Unlike previous requests 
where I didn't provide a good way to use it, I now have a tarball with 
installer:

I would welcome help cutting down memory taken by large datasets.

Thanks in advance,
