Hi, Luminus uses Immutant, which uses Undertow, so it should be possible to tune the Luminus app to approach the performance of the TechEmpower Undertow app. The relevant options to immutant.web/run [1] are :dispatch?, :io-threads, and :worker-threads.
The Undertow app sets IO threads here [2] and worker threads here [3], so you can easily set those same values in the Luminus app. But the real performance bump will come from the :dispatch? option. By default, :dispatch? is true, i.e. requests handled by threads in the IO pool are dispatched to a thread in the worker pool. For compute-bound tasks like the JSON serialization benchmark, that context switch is far more expensive than just having the IO thread return the response. So you'd want to set :dispatch? to false in that case. The tricky bit here is that the Luminus app defines all its routes in a single handler [4]. But for the more io-bound tasks, e.g. DbSqlHandler [5], you'll want the default true value of :dispatch?. So in order to get the best results for all the benchmarks, you'll need to re-organize that app to run two handlers: one that dispatches and one that doesn't. In Immutant, the simplest way to do this is to distinguish each handler with a unique :path option. I'm happy to assist whoever is maintaining that app with the tuning.
