I`m running an Ubuntu 16.04 guest on a Ubuntu 14.04 host in VirtualBox.
On the host, I have an Wordpress installation in the folder
/home/myuser/wordpress. I add this folder to the "Shared Folder" list in the guest machine VirtualBox settings.
Then I configured the apache on the guest machine, so that he loads the website from this shared folder. Everythings works, but it is very slow (10 seconds for a Wordpress backend load).
When I copy
/home/myuser/wordpress to the guest machines virtual drive, e.g. in /var/www/wordpress on the guest, and point apache to that folder, it runs in 2 seconds.
Why is the virtual box share so slow? And are there possibilitys to increase the performance? Or are there another possibilities to share files between host and guest?
