I install Magento 2.1.2 on a vagrant powered virtualbox with Ubuntu 16.04 64bit with 4GB RAM and 2 processors on a MacBook Pro 2015 with 16GB RAM and 2,9 Ghz Intel Core i5. I have faked a domain https://www.testing.com for that box. Magento is installed in a subdirectory https://www.testing.com/shop
On the machine itself the folder structure in short is:
/var/www/share/testing.com/htdocs (webroot) -> symlink to /var/www/share/testing.com/cms/current
/var/www/share/testing.com/cms/current -> symlink to /var/www/share/testing.com/cms/deploy/<datetime>/htdocs
/var/www/share/testing.com/cms/deploy/<datetime>/htdocs/shop -> symlink to /var/www/share/testing.com/shop/current
/var/www/share/testing.com/shop/current -> symlink to /var/www/share/testing.com/shop/deploy/<datetime>/htdocs
Already the installation is super slow. With the web wizard it fails to install as it gets stuck at installing the user configuration.
As adviced in other tickets I thus install it via composer and commandline. But also on the commandline "generating autoload files" takes >5min.
After the successful installation the whole bare shop is super slow. Pages take >1min to load. No difference in the backend. Deploying static files does not change the behavior.
Changing to production mode is impossible as it generates seemingly infinitely. I let the script run for about 3 hours until I stopped it.
One other thing that is strange is that all scripts run with "php bin/magento ..." take a lot of time to "start". I send the command and then it takes about a minute to actually produce the first output. After it produces the first output the scripts seem to run at a fair speed (except the one for switching to production mode). This happens for everything I do. Like clearing/flushing caches, deploying static files, installing and so on.
Maybe there is a problem with the autoloader? Could that time be the time the autoloader indexes all needed files?
Well anyway the question is: why is my Magento slow? What else could I do find the reason?

This is the install command I use:
php current/bin/magento setup:install --admin-firstname=xxx --admin-lastname=xxx --admin-email=xxx --admin-user=admin --admin-password=admin1234 --base-url=https://www.testing.com/shop/ --backend-frontname=xxx --db-host=localhost --db-name=xxx --db-user=xxx --db-password=xxx --language=de_DE --currency=EUR --timezone=Europe/Berlin --use-rewrites=0 --use-secure=1 --base-url-secure=https://www.testing.com/shop/ --use-secure-admin=1 --admin-use-security-key=1 --session-save=db --cleanup-database
I tried with use-rewrite on and off. No change in behaviour though.

Here is a har file of the second call of the frontend: https://gist.github.com/anonymous/318d183e1be5d4ea5b674654c8fc5f0e
You can view it in http://www.softwareishard.com/har/viewer/
Also I attached a htop screenshot while loading the admin backend.
And one other thing I found strange is the admin url:
https://www.testing.com/shop/index.php/zoo/admin/index/index/key/<key/
Why is are there 2 index
in there?
/var/www/share/testing.com/cms/current/
run smooth as expected
