在 docker 执行 git 很慢是什么原因?

已知 docker 在 Mac 下，映射进去的目录，小文件性能很差。

docker 运行的容器是 overlayfs 文件系统，写入慢，用--mount 挂载 host 上的的路径进行读写就快一些。
参考：
https://docs.docker.com/storage/storagedriver/overlayfs-driver/
https://docs.docker.com/storage/bind-mounts/

挂个 mem 盘进去看看，是不是磁盘导致的

@amrnxcdt 你好我用了 --mount 命令测试感觉还是没有快多少, 而且设置时间的命令也用不了

sudo docker run -d --privileged -it \
--mount type=bind,source=/datastore1/x9,target=/host \
--name sd_build_x9 sd_build_3 /bin/bash

@yhm2046 #4 你要提供更多信息大家才能帮你判断。比如你的 docker 版本和 host 系统是什么？ docker 镜像是什么系统、镜像内和 host 上的 git 版本什么的。

@amrnxcdt 宿主机器:
Docker version 20.10.17, build 100c701
Description: Ubuntu 22.04.1 LTS

docker 镜像
sudo docker exec -it df01ded745cd /bin/bash
git version 2.7.4
Ubuntu 16.04.7 LTS

另外设置时间问题我已经解决了,参考 https://blog.csdn.net/ju_362204801/article/details/114383191
不过现在在 docker 里面编译出现报错, 我怀疑是挂载命令出错,因为我用-v 挂载是可以正常编译没有问题的
//原来的命令
sudo docker run --privileged -it -d -v /datastore1/x9r:/host --name sd_build sd_build_3 /bin/bash
//报错 log

@yhm2046 #6 -v 和--mount 就是默认参数的区别，参考： https://docs.docker.com/storage/volumes/#choose-the--v-or---mount-flag

参考 make 的错误是 Entering directory ，应该是--mount 缺少参数了，如果-v 可以用直接用-v 就行。
