some AB testing ...

Yes, as long as the tests are done against simple « Hello World » alike queries. In real world, with SQL well urbanized db, we have to expect that all performance (Openresty ones included) will slow down from 35% (very cleanly modeled applications + sql back-ends) to the infinite (sad ones, alike those using, in the PHP world, Symphony2 or unreliable db models designs).

About size and needed processing on the datas, the application server will stay very responsive and scalable along loads as long as the SQL back-end will be designed to get the best from its own (one request peer view including complex joints each time it’s possible).

Mainly a Livecode standalone (+ accessories : templates engines, JS frameworks, etc…) receiving requests on a TCP socket entry point, handling the preparation of the response in querying/writing the needed datas from/to the SQL back-end before sending it back to the client via the socket.
