Just curious, what database were you using that wouldn't keep up with
you?  I use PostgreSQL and would never consider going back to flat
files.  The only thing I can think of that might make flat files faster
is that flat files are buffered whereas PG guarantees that your
information is written to disk before returning but if speed is more
important than 100% reliability you can turn that off and let PG use
the file system buffering just like flat files.
