Hello,

I run a webserver with nginx and php-fpm on a 1Gb linode, I use php opcache.
I was wondering if I should also use varnish.
I read online that it can be a better choice to use nginx only because it can also does what varnish does, varnish is also memory consuming (consiering 1Gb linode).
What do you think ? is that right?
Do you think that using varnish in front of nginx is a waste of time/memory?

thank you
