personally I would expect that exec (spawn + piping) to have less transmission overhead than http query even on connection reuse (building http message + network communication + parsing headers), but actually the reason I wrote is to point that if someone is concerned of the overhead and not sure what option to use, it can measure the performance with benchmark module. Also, to be clearer, execution of a lua/python/... script via app_lua/app_python/... is not external script execution, the interpreter is embedded, so it is internal execution. This is definitely faster and preferred option compared to exec or http query.
