Overview

Mounting in Docker for Mac is slow. npm and other operations are painfully slow. This is a memo.

Cause

Refer to the comments from Docker staff. (See the middle section of the linked page)

Docker - File access in mounted volumes extremely slow, CPU bound

It seems related to the file system API of MacOS.

Solutions

• Use Windows or Linux
• docker-sync
• Set up a virtual environment built on an OS different from MacOS (like Vagrant)
• Utilize options like cached, delegated, consistent (Docker - Performance tuning for volume mounts (shared filesystems))

Thoughts

I feel like I want to use Linux.
