Low performance of Ruby on Rails in Docker under Windows

You can improve the performance of Ruby on Rails in Docker under Windows 10 if you run docker-compose not from Windows, but from WSL.

For example, if the source code of the project is in C:\Users\user\projects\myproject, you need to copy it to WSL - /home/user/projects/myproject

The WSL file system from under Windows is accessible via \\wsl$, you can copy myproject via File Explorer or terminal from C:\Users\user\projects\myproject to \\wsl$\Ubuntu-20.04\home\user\projects\

Then, using your favorite distribution, run WSL, go to the directory with the copied code and run docker-compose

cd ~/projects/myproject
docker-compose up -d

To edit code from Windows, you can open the \\wsl$\Ubuntu-20.04\home\user\projects\myproject directory in your favorite editor

In my case, the rendering speed has increased by about 10 times.
