PHP7.0-fpm extremly slow on Ubuntu Windows Subsystem Linux - nginx

Question

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.
I am sure that php is slower by observing that if i load a static file i.e a txt or html files, it loads blazingly fast.
Below are my sites enabled files and nginx conf file ..

Error logs for both nginx and php-fpm working, nothing being logged against errors.

Answer 1

Using windows 10 v1803, and nginx & php7 fpm via WSL.
Changing listen to 127.0.0.1:9000 doesn't work for me.
After spending hours of googling, I found:
https://github.com/Microsoft/WSL/issues/2100
i.e. Add
fastcgi_buffering off;
to nginx.conf, and save my day.

Answer 2

Sorted this out, pasting for any other enthusiast working with ubuntu on windows subsystem.
The default Nginx and php setups are going to use a unix:socket, but that’s not going to work for WSL. Also, WSL uses a lightweight init system and services are not going to start automatically for Nginx, PHP, MySQL, etc.
Edit /etc/nginx/sites-available/example.com.conf
comment out fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
and add fastcgi_pass 127.0.0.1:9000;
Edit /etc/php/7.0/fpm/pool.d/www.conf
comment out listen = /var/run/php/php7.0-fpm.sock;
and add listen = 127.0.0.1:9000;
It will fix all of your issues.
