“ According to my preliminary tests, using Crack makes you 5 to 10 times more productive than using Rails. Not only that, but speed wise, you’re running much faster with Crack. … Part of the speed boost that Crack can give you, is due the highly efficient, thread-safe and powerful ORM called Freebase. Even Datamapper is really slow compared to Freebase. On average, Freebase smokes ActiveRecord (it’s 4 to 5 times faster).
