Oh, much worse than I thought. How can they justify this price tag? Anyway, Nginx + LuaJIT (custom-build, Tengine, or OpenResty) beats both plain Nginx caching

Oh, much worse than I thought. How can they justify this price tag? Anyway, Nginx + LuaJIT (custom-build, Tengine, or OpenResty) beats both plain Nginx caching and Varnish. I was considering using Varnish in front of Nginx with PageSpeed, but given the direction they are taking, I'm sticking with Nginx although it's taking a similar dangerous direction recently.
