问题 I installed Windows Subsystem Ubuntu shell recently and shifted all of my development from XAMPP to nginx and php7.0-fpm installed through ubuntu windows subsystem. The problem i am facing is that php files load extremly slower. For a test I simply put <?php phpinfo(); ?> in a file and executed it. It literally took the system two minutes to return the reply. I have debugged a lot but could not find any solution. I am running nginx through nginx server blocks and have setup my local domains.
