| 1 | Given that todays processors ship with dual or quad cores and server processors ship with between 8 to 32 cores, languages like Java, Ruby, Groovy and Python are struggling to keep up. | ||
| 2 | |||
| 3 | Scala, as its name suggests is built from the ground-up for concurrent programming - a methodology that can take advantage of these modern multi-core processors. | ||
| 4 | |||
| 5 | If you use Scala for a concurrent programming, the chances are that you're using Scala Actor to do that. | ||

| 9 | EOF being notoriously single-threaded, is incredibly unsuitable for use by Scala Actors. | ||
| 10 | Instead you may still use EOF but only to execute SQL directly. | ||
