I have been benchmarking different usage scenarios for sharing files between hosts and VMs for the past couple years, and for the majority of use cases, the only way to get near-native performance without much hassle is to use Vagrant's rsync support instead of native shared folders or even NFS, which exhibits some jitter making it annoying at times. See: http://www.midwesternmac.com/blogs/jeff-geerling/nfs-rsync-and-shared-folder http://www.midwesternmac.com/blogs/jeff-geerling/nfs-rsync-a... If your project doesn't have hundreds or thousands of files, or if you don't need as fast filesystem performance on your host machine, there are other ways that might give more convenience. But I stick with rsync/rsync-auto for 99% of my VMs, whether using VirtualBox or VMware.
