I don't think Rails is faster than Java, because Rails is only web based and Java is everywhere. Java is much enriched and full of resources. Its community is also vast. Plus its celebrating its 20th birthday and Java is still rising, and Rails is only 9 years old. But in such short time Rails also got good popularity. Sites like Shopify, Cruncbase,SoundCloud used Rails. Twitter was also based on Rails but they are moving their codes in Java recently. We never know in future Rails could beat Java in web developments.
