Many developers at my organisation are being affected by the issue https://github.com/docker/for-mac/issues/668
Builds which include DB2 manipulation take up to 20 minutes where on Linux they take just 90 seconds. We create docker containers with DB2 and run scripts against the database regularly so this is a problem for the developers here with Mac OS.
The issue doesn’t appear to be being worked on though, is any action planned?
