we are using Docker for Windows since a while. Today I came up with something really strange. Prior Docker for Windows I had a folder C:\User\Daniel\myFolder made available via a network share - so going to the windows explorer and adding the folder as share with permission for everybody to read and me to read/write.
Then we started using Docker for Windows - everything works fine and fluid. We use Docker for a large scale php project with many files / classes.
Today I detected my old network share and switched it off. Docker still runs stable - but performance dramatically reduced by a factor of 5-10 for file access on the volume. When I added back the network share on this specific folder -> tada - performance is back. For me it seems as if there are some settings which might improve performance for volumes in windows which are currently not yet set by Docker for Windows. A workaround for this seems to be manually adding the specific folder as a network share. But I gues this might be worth to figure out wether this setting could be used by default in docker for windows so that new users won’t have the speed issues.
Are there any other users seeing the same issue or can test it?
PS: Our configuration is Windows 10 Pro used in a domain setting / active directory
