File sharing extremely slow for lots of files

[steffenbrem]

The volume mount is unusable to use for me. I need to share thousands of PHP files (it’s a Symfony2 web app) and the execution time is around 20 seconds. When running the same docker containers in a boot2docker image over NFS (VirtualBox) it performs in milliseconds. Any idea if something might be wrong with my setup? How would I setup a proper NFS connection between my host OS and a container running in the Docker app.

How to speed up shared folders

I don’t know what I’m doing wrong but I’ve installed Docker for Mac and have now problem with fast accessing hundreds of files in shared folders. I’m using docker for developing symfony2 applications and as far I was using docker-machine-nfs with machine created on virtualbox using docker-machine. When I wasn’t using nfs loading times per page was hitting around 10 seconds making this extremely slow to develop. Using nfs fixed the issue, loading times were around 100-300ms like on local environ…
