I thought I would put this together quickly because in typical Linux fashion something that should be straightforward isn’t… Node.js – I am still not sure what it is :), however I am in the process of setting up drupalchat on one of my sites and when I tried using it with the AJAX option, which worked well for a couple of users, it made the site run extremely slowly. The server has plenty of grunt… dedicated Ubuntu 13 VM running 3 cores and 2 GB of RAM and this particular site was the only thing running on it. Furthermore, the MySQL database server was/is on a separate dedicated VM… so there is no way it was a lack of firepower. DrupalChat running with AJAX was causing problems. I am going to launch a fuller tutorial on getting drupal chat setup but I figured I would do the node.js thing here and now….
