As Mithun suggested, it's going to be slow regardless of which web server option you choose. 

It depends on your application, but if it's a user-facing web application, one way would be to have your client application make an API call to your backend, the backend enqueues the job in the queue, the queue worker/consumer does the work and puts the result in a result store, and your application front-end either asynchronously polls (using Javascript) or has a refresh button that lets the user check for their predictions/recommendations. 

Or if you don't want to use the job queue, 100-500ms isn't too bad to just do an AJAX call from the front-end to your Mod_perl API backend. Have your web page load quickly, then do the slow work asynchronously (one way or another). That's how most modern user-facing web apps work, and it works pretty well.  

If your app isn't human-facing, then I don't see why a little delay would be a problem?

yes, this is a prediction server, which would be deployed in PROD environment, the client application would request the prediction server for results as scores. You can think it as online recommendation systems.
