Apart from the configure options at build time you should read -
http://www.sqlite.org/pragma.html

It was a few versions ago so may be changed by now, but I reckon it
was the temp_store setting - which is described as temp tables and
indexes but is (or was) also used for large query and sorting needs.
Setting this to memory did make a difference for some queries.
