That's odd. I would check how you have Keep-Alive configured and how long you let the mod_perl processes live (MaxRequestsPerChild) in both cases. Nginx should be just fine as a proxy. > In your slideshow you talk about using Apache with a threaded worker MPM as > the frontend and a prefork MPM as the backend.

It's mod_proxy configuration. There are lots of guides on how to do it, including some on the mod_perl site. Search for mod_proxy or reverse proxy. - Perrin
