Are you sure? Summing the 'memory' info items below
gives me 52 million words, or 208 megabytes.

11 minutes is still a lot. When playing with a 64-bit
machine, I was able to load 5 million records from disk
in about 27 seconds. That was one table occupying about
686 MB of RAM.

Do you have a thread pool enabled? (+A 255, for example)
