I had Magento 2.0.4 instance running on vagrant machine:
- CentOS 6.5
- PHP 7.0.1
- MySQL 5.6.31
I've upgraded to 2.1 with composer but then when I tried to run
php bin/magento setup:upgrade
I get noticed that PHP version is not supported and needed to upgrade [release notes]. So I've upgraded to PHP 7.0.8 and then my Magento starts to work very slow (about 45 sec for any frontend page). I tried to downgrade Magento to 2.0.4 but still working slow. I assume that is from the PHP version upgrade.
When I turned on caches it works normal.
Did anyone had this issue and know how to resolve it?
