Github user robertdale commented on the issue: https://github.com/apache/tinkerpop/pull/498 @okram The giraph improvement will help all builds inside or outside of docker. That should save you about 1 hour. I don't know what OS you're on, but in Linux you can get some speed improvement if your fs is mounted with noatime (and lazytime on newer kernels). For the ultimate speed improvement, you can make your changes on the regular fs then copy up to an in-memory fs (e.g. tmpfs) and then build there. That should save 20m just on neo4j and several more overall.
