Yes Erlang is: 1. so much faster to execute 2. much faster to code with 3. much faster and easier to maintain your code definitly 4. much smaller size of effective code compared with Java 5. MOST IMPORTANTLY: Erlang has the ability to adjust your running code and patch your system while it is up and running! and maintain versioning for your patches dynamically, this means that you're guaranteed 99.99% of systems availability. Erlang is a pioneer in Soft Real Time computing. Virtually systems written in Erlang never go down. it has been designed for the telecom sector at the beginning and was tested rigorously for that at Ericsson Labs.

hope this helps..
