The SRP Engine Server allows you to setup an asynchronous engine farm. It was built with speed in mind, so it spins up as many engines as you request at startup and keeps them alive as long the server is up and running. This allows you to very efficiently hand off many self contained tasks in a fire-and-forget model. For example, you could write an MFS that sends a command to the engine farm to synchronize a record to another database at the moment it's being written without delaying the client. You can use it for a data processing center in which thousands of tasks arrive in a minute and are distributed to several waiting engines.
