The remote execution service is currently using Raven, which means that on the first run it can take several minutes before workflow execution starts, due to downloading of Maven artefacts. In addition, on subsequent startups Raven spends 5-10 seconds scanning various POM-files, which means executing a workflow (since we are currently fork-ing per execution) can take up to 15 seconds even in the simplest helloworld example. The suggested fix is to use the raven.eclipse system property and depend on the neccessary processors.
