File access in mounted volumes extremely slow, CPU bound

Docker Desktop
240

I am experiencing the same issue with docker mac 1.12.3-beta30.1 - brutally slow compared with docker machine on linux which we are using as the testing host. Its strange as it wasn’t too bad, and it does seem to vary. I have not been able to put a pattern to it as yet. Prior version seemed better than this one does though. I am in this case using neo4j database with database on volume.
