Yes, wonderful for cases where one can *practically* fit the entire database
in memory. As soon as you get into a database that must store some serious
amount of data, such performance claims are rather useless. Such claims also
depend on the fact that your writes are never saved to disk for the duration
of the tests - wonderful for a real application should the power go out!
