Grunt watch detects file changes only after 5 seconds with Vagrant and NFS

Question

Grunt watch (grunt-contrib-watch) is used to trigger reload of web app in browser. However, it is slow to notice file changes when running in a Vagrant virtual machine usin

Answer 1

Try these mount options in your Vagrantfile:

type: "nfs", mount_options: ['actimeo=1']

This will greatly reduce the NFS file attribute caching timeout. I was having similar troubles, seeing large delays with Vagrant/NFS when waiting for gulp and Django server reloads. This fixed it; file changes are now detected instantly.
