So in my learning as I'm going development of a site for a group of friends I set up a digital ocean droplet (the smallest size one) and install the ghost blog platform on the main domain and nodebb for the forum. subdomain and the reverse proxy stuff is being handled by nginx. However with this install I'm having an issue with nodebb running very slowly, for example when I launched it for the first time and went to the forum.domain.com address the top navigation bar loaded pretty much straight away but the categories didn't for about 8 seconds.
Now this is the first time I've had more than one node.js app running on the same VPS so I'm wondering if I need to use a bigger droplet (Though I did try a 2 core 2Gb resize though that seemed to make no difference) or if I've screwed up the nginx setup somehow (though I would have thought that would slow down the ghost blog as well, which is running fine.) or if something else I can't even think of is happening (likely, I am not a bright man).
Any help/thoughts would be appreciated.
