Hey I will upload some comparisons when I get home and remember.
Also I should note something else I have come across. It's probably best not to edit the server block EE created. Rather than to creat a .conf file in domain/conf/nginx/mysettings.conf
It will automatically be included.
Also I wanted to add an extra server {} block to redirect http to https which I originally did editing the required server block. It's best to do this the old fashion way e.g.
nano /etc/nginx/sites-available/custom
add in fields there that can't be done using the previous method.
Then
ln -s /etc/nginx/sites-available/custom /etc/nginx/sites-enabled/custom
That way when EE updates or you change your cache method your site won't go down.
Took me a bit to figure out what went wrong when I changed my cache method and it wipes the server block to stock.
