我不确定要提交哪些其他信息来调试这种情况。有什么可以提高性能的吗？
众所周知，在 VirtualBox 中挂载主 (mac) 文件夹的数据传输速度极慢。尝试使用 Docker 代替 Mac，或将您的内容复制到命名卷。例如：
docker create volume --name myvol
docker run --rm --name data-container -v myvol:/data alpine top
docker cp dir/with/files data-container:/data
docker rm -f data-container
这为您提供了一个卷 myvol，您可以将其装载到任何容器上。卷数据保存在 VirtualBox 主机中。
要加快速度，您还可以使用 http://docker-sync.io - 它是在 OSX 下专门为这种情况构建的。
