Is small sidestep allowed? Are unicorns similar thing than workers of PHP? Some document tried explain that unicorns are actually HTTP-servers with own workers delivering requests to Ruby, and that’s why it is totally different. But both handles http-reguests allowing more concurrent requests and therefore more PHP-workers and more unicorns need more RAM — and for me those two are pretty much same.
Right or horrible wrong? I would like to understand the principle now, because I know why, when and how to adjust PHP-workers, but unicorns are just mystical and magical creatures for me.
