Docker Volume Mount Performance Issue on Mac

Issue

There’s a performance issue on Mac.
In my case, the docker.hyperkit process is using high cpu resources.
You’d better use cached configuration in conclusion.

Tuning Configuration

Configuration	Description
`delegated`	The container’s view of file system writes performed by containers my not be immediately reflect on the host file system.
`cached`	The `cached` configuration provides all the guarantees of the `delegated` configuration, and some additional guarantees around the visibility of writes performed by containers.
`consistent`	This is default. The container and host are always synchronizing.

Examples

Volume Mount with Default Configuration as `consistent`

1
docker run -v /host/data/:/var/lib/mysql mariadb:latest

Volume Mount with `delegated`

1
docker run -v /host/data/:/var/lib/mysql:delegated mariadb:latest

Volume Mount with `cached`

1
docker run -v /host/data/:/var/lib/mysql:cached mariadb:latest
