Hi Livecoders,

Story made short : Appart the amazing Lua platform (preferably set as an Openresty one), well configured LC application’s servers still outperforms anything available around (Websphere, Tomcat, PHP5/7, Perl5, NodeJS, Go, Python, RoR,…). In-between, LC application’s server is 60 times faster than the stock’s Livecode CGI Server. Using Nginx as the load balancer of the same LC app running on clustered front-end servers can make a very reliable scalable configuration : 1500 connections for each server added to the cluster. In taking care to scale the ACID-SQL backend cluster as attendee, the platform can handle very high-end solutions at a fraction of the cost of more known main stream proposals.

What the story don’t tell is that the still mono-theaded LC engine don’t crashes nor slowdown against heavy loads where Java powered ones does (mostly because Java’s heap space shared memory unreliability and the cache misconfiguration surprises) and PHP too, because too many unreliable frameworks used in front of it (Symphony 2, etc…).
