Hi Stan

You should be able to set those advanced options in your sphinx.yml  
file - they're not listed on the docs page, but they will get passed  
through to the generated configuration file.

That said, I've no idea what settings will make your indexing speeds  
faster (or less memory intensive) - but try changing them, see what  
makes it all faster/smoother, would love to hear some solid numbers.

Cheers
