TINKERPOP-1557 Improve docker build time with this one weird trick!
Total time went from just over 4 hours to 2:20m. Get back 1:40m of your
cycles!
Giraph: startup would wait 3s to connect. solution: wait less. There's
still about 7s for shutting down that can be gained back per test!
Neo4j: very disk IO heavy. solution: work in memory. this benefits the
entire build as well. This requires something special below.
In order to build in-memory, you must configure tmpfs with the magical
directory name `/usr/src/tinkermem`.
example:
```
export DOCKER_OPTS="--tmpfs
/usr/src/tinkermem:exec,mode=0755,rw,noatime,size=1000m"
```
You can use `1000m` for typical `-t -i -n` usage. Use `2000m` if building
javadoc, asciidocs.
I will add some of this to the docker contributing /
development-environment docs.
