The reason index creation slows down when creating large indices is a problem with locality of reference in your disk cache. I've learned a lot about dealing with locality while working on full-text search, and I think I can probably implement a CREATE INDEX that runs much faster for a large table. There are some plans in the works that might permit me the time to do this in the spring. But in the meantime, the only thing I can suggest is to add more RAM to your machine so that you disk cache is larger. Or get a faster disk drive. -- D.
