forked from External/greenlight
4286864263
We noticed that the current default settings perform very poorly under load. We managed to literally take down Greenlight during a larger event when people where accessing the landing page for rooms and when doing some tests, I was more or less able to DoS Greenlight on my own. This patch adds a default worker configuration similar to the previous configuration with one worker, but lets users easily adjust it to more workers which significantly improves the situation. The small, 4 core machine I was testing on could handle about thrice the amount of requests. Co-authored-by: Ahmad Farhat <ahmad.af.farhat@gmail.com>
